Seasonal Luxury Bag Silhouette Planning Calendar
A seasonal silhouette calendar works backwards from the delivery window, not forwards from the drawing. Four quarters drive it: spring, resort, autumn and holiday, each with its own proportion, material and hardware requirements. With sampling at 6-10 working days, a complex build at 12-15, and bulk production at 35-50 days, a brand that counts backwards from the delivery date knows exactly when a tech pack has to be final. This guide answers the planning questions in the order a brand asks them.
What Does a Seasonal Silhouette Calendar Actually Plan?
A seasonal calendar plans decisions, not drawings. It fixes when a tech pack is final, when the first article is approved, when the bulk order is placed and when the cartons have to leave, for each of the four quarters. It also fixes what does not change between them, because a collection that reinvents its leather grade, its hardware finish and its stitch density every quarter never builds a recognisable house style, and it spends four sampling rounds a year discovering specifications it had already solved once. The calendar is therefore as much a list of what is frozen as it is a list of what moves.
The planning unit is the delivery window rather than the season. A brand that starts from a spring delivery date and counts backwards through 35-50 days of bulk, 6-10 working days of sampling and a week of tech pack finalisation arrives at a start date that is realistic. A brand that starts from a mood board arrives at a start date that is aspirational, and the difference is usually four to six weeks of avoidable pressure at the end.
The one-line answer
- Count backwards from the delivery date: 35-50 days of bulk production, 6-10 working days of sampling (12-15 for a complex build), plus a week to finalise the tech pack. Anything that must change in the seasonal language is decided before that start date, not during it.
When Should Spring Silhouettes Be Sampled?
Spring assortments are the lightest in construction and the widest in proportion, which is what makes them the right place to try something new. They favour a semi-structured body with a concealed base plate, a gusset of 6-8 cm and a lighter lining at 120 gsm rather than a heavier split suede. Sampling is fast, at 6-10 working days, because few spring pieces carry a blocked frame and none of them needs the longer cooling and measuring cycle that a structured autumn body does. That speed is the reason spring is the safest quarter for a brand to introduce a new silhouette.
- Construction: semi-structured with a concealed base plate rather than a blocked frame.
- Gusset: 6-8 cm, keeping the profile light for the season.
- Lining: 120 gsm jacquard rather than a heavier split suede.
- Sampling window: 6-10 working days, which makes spring the safest quarter for a new shape.
What Changes for a Resort Assortment?
Resort is the quarter with the most specification change and the least silhouette change. The shapes carry over from spring; what changes is the hardware and the finish. Because resort pieces meet sun, salt and humidity, hardware is plated to the top of the 0.15-0.3 micrometre band and tested for 48 h of neutral salt spray rather than 24 h. Leather selection shifts towards grained calf at 1.4-1.6 mm, which hides abrasion better in that market.
Hardware
Plated to the top of the 0.15-0.3 micrometre band, and tested for 48 h rather than 24 h.
Leather
Grained calf at 1.4-1.6 mm, which hides abrasion better than a smooth full-grain in a coastal market.
Colour
Matched under D65 lighting and held as a physical standard, because sun exposure shifts perception.
Silhouette
Carried over from spring rather than redrawn, so the quarter costs one sampling round instead of two.
How Do Autumn Silhouettes Differ?
Autumn is the structured quarter. Bodies get taller, gussets go to 8-10 cm and blocked frames return, because a customer carried a coat and a document sleeve and the bag has to hold its geometry against heavier clothing. This is the quarter where the 12-15 working day sampling window applies, and it is the quarter that has to be started first in the calendar even though it is not the first to deliver.
- Body height
- 26-30 cm, taller than the spring band
- Gusset
- 8-10 cm, and a reinforced base
- Frame
- Blocked and laminated, the reason for the longer sampling window
- Sampling
- 12-15 working days, so autumn starts first in the calendar
- Hardware
- Back to the standard 24 h salt-spray specification
What Does a Holiday Assortment Need?
Holiday is the smallest quarter in volume and the largest in margin per unit, and it is specified almost entirely around the evening piece. Bodies drop to 18-20 cm, gussets to 5-6 cm, and closures come from the same cast family used across the line but scaled down rather than newly tooled, which keeps the line reading as one house at the smallest scale. The critical planning fact is that holiday hardware still has to be ordered before the autumn bulk is finished, because a custom casting carries its own tooling lead time.
- Body height 18-20 cm and a gusset of 5-6 cm, on a slim frame.
- Closures from the existing cast family, scaled down rather than newly tooled.
- Hardware ordered before the autumn bulk finishes, because tooling has its own lead time.
- The highest margin per unit in the year, and the smallest volume.
How Far Ahead Should a Bulk Order Be Placed?
A bulk order needs 35-50 days from an approved sample, and the approval date is the one most brands underestimate. Add the sampling window, the correction round that most first articles need, and the week it takes to finalise a tech pack, and the honest planning figure is sixty to seventy days from a finished drawing to a shipped carton, plus packing and port handling at the end. Brands that plan on the 35-50 day figure alone are the ones asking for air freight.
- Tech pack finalisation: allow one week before sampling can begin.
- Sampling: 6-10 working days, or 12-15 for a complex build.
- Correction round: allow one further round on any new silhouette.
- Bulk: 35-50 days from an approved sample, then packing and shipping.
How Do You Keep a Core Shape Out of the Seasonal Cycle?
A core shape is the piece that does not change between quarters, and it is what makes a brand recognisable. It is specified once as a frozen tolerance sheet covering body dimensions, drop, stitch density, plating thickness and edge coats, and it is reordered rather than redrawn. Seasonal change then happens in colour and in the pieces around it, which is a far more efficient way to spend a sampling allowance.
| Element | Seasonal pieces | Core shape |
|---|---|---|
| Body dimensions | Change with the quarter | Frozen on a tolerance sheet |
| Leather grade | Changes by season and market | One grade, held every run |
| Hardware | Seasonal finish, one family | One metal, one finish, forever |
| Colour | Changes every quarter | Two permanent colours, plus seasonal |
| Sampling | One round per quarter | No sampling on a reorder |
| Audit | AQL 2.5 against the new first article | AQL 2.5 against the original sample |
How Do You Brief a Quarter?
Each quarter needs its own brief, and the brief is four documents rather than one mood board. A dimensioned drawing fixes the silhouette. A tolerance sheet fixes the bands we audit against. A material call-out fixes the leather grade, the lining weight and the hardware specification. And a delivery date fixes everything else, because it is the number the whole calendar is counted backwards from.
- Dimensioned drawing: body height, width, gusset depth and drop marked on the drawing.
- Tolerance sheet: the bands audited at AQL 2.5, agreed before sampling rather than after.
- Material call-out: leather grade and thickness, lining weight, hardware metal and plating.
- Delivery date: the figure the calendar counts backwards from, and the one never to leave vague.
- Carry-over note: which elements are frozen from the previous quarter, stated explicitly.
What Is the Four-Quarter Calendar?
The table below is the calendar we give a brand at the start of a planning year. It sets out what each quarter specifies, which specification lines change and how long each build takes. It is deliberately conservative on sampling time, because a calendar that assumes a perfect first article is a calendar that slips.
| Quarter | Silhouette bias | Specification change | Sampling window |
|---|---|---|---|
| Spring | Semi-structured, light profile | Lighter lining, 6-8 cm gusset | 6-10 working days |
| Resort | Spring shapes carried over | 48 h salt spray, grained calf | 6-10 working days |
| Autumn | Structured, taller bodies | Blocked frame, 8-10 cm gusset | 12-15 working days |
| Holiday | Evening and small pieces | Scaled closures, 5-6 cm gusset | 6-10 working days, tooling first |
What Are the Three Planning Mistakes?
Three mistakes account for most slipped calendars, and all three are planning errors rather than production errors. The first is planning bulk on the 35-50 day figure and forgetting the sampling window that precedes it. The second is changing the leather grade in a resort quarter without moving the salt-spray specification with it. The third is tooling new holiday hardware after the autumn bulk has already started.
- Counting bulk time only, and forgetting sampling, corrections and tech pack finalisation.
- Changing the leather for resort without moving the hardware to a 48 h salt-spray specification.
- Tooling holiday hardware after the autumn bulk has started, which collides with production capacity.
Sampling, MOQ and Shipping Terms
Across all four quarters the commercial terms stay fixed. A first article takes 6-10 working days, extended to 12-15 for a blocked frame, a custom cast closure or a mixed-media panel. Minimum order quantity is 500 pcs per style / colourway, bulk production runs 35-50 days from an approved sample, and every shipment is offered FOB Xiamen. Specified programmes begin at USD 4.80 per unit.
Our validated partner factory Quanzhou Yingming Bags has run seasonal calendars since 2014 on 7 production lines with a monthly output of about 200,000 pcs, which is what allows four quarters to be planned in parallel rather than in sequence. Every shipment is audited at AQL 2.5 (ISO 2859-1) against the approved first article, so a core shape reordered in a later quarter matches the original unit for unit.

Frequently Asked Questions
How far in advance should I plan a seasonal bag collection?
Sixty to seventy days from a finished drawing to a shipped carton. That is one week of tech pack finalisation, 6-10 working days of sampling, an allowance for one correction round, and 35-50 days of bulk production. Planning on the bulk figure alone is what forces air freight.
How long does bulk production take for a handbag order?
Thirty-five to fifty days from an approved sample, offered FOB Xiamen. The range exists because a soft body moves faster through the line than a blocked frame with a hand-set lining, and because a reorder on a frozen tolerance sheet moves faster than a new silhouette.
Which season needs the longest lead time?
Autumn, because structured bodies with blocked frames take 12-15 working days at sampling rather than 6-10. Autumn is therefore the quarter that has to start first in the calendar, even though it is not the first quarter to deliver to the customer.
Should a resort collection use the same shapes as spring?
Yes. Resort changes specification rather than silhouette: hardware moves to the top of the 0.15-0.3 micrometre band and is tested for 48 h of salt spray, and the leather shifts to grained calf at 1.4-1.6 mm. Carrying the shapes over saves a full sampling round.
Why does resort hardware need a longer salt-spray test?
Because resort pieces meet sun, salt air and humidity. A 24 h neutral salt-spray test is the standard specification; resort and coastal assortments are plated to the top of the band and tested for 48 h, which catches plating that would show base metal within one season in that market.
How do I keep a core shape consistent across seasons?
Freeze it as a tolerance sheet covering body dimensions, drop, stitch density, plating thickness and edge coats, keep the approved first article as the physical standard, and reorder against it. Seasonal change then happens in colour and in the pieces around the core shape.
What is the minimum order quantity per season?
Five hundred pieces per style and colourway, in every quarter. A brand running four colourways of one core shape across a year places four qualifying runs, and the threshold covers the frame tooling, the hardware setup and the pattern planning each time.
When should holiday hardware be ordered?
Before the autumn bulk has finished, because a custom casting carries its own tooling lead time. Ordering holiday hardware after autumn production starts is the third most common planning mistake, and it collides directly with production capacity on the line.
Can four quarters be produced in parallel?
Yes, and that is the point of a calendar. Our validated partner factory Quanzhou Yingming Bags runs 7 production lines with a monthly output of about 200,000 pcs, which is what allows a spring reorder, an autumn bulk and a holiday tooling to run at the same time.
How much does a seasonal programme cost per unit?
Specified programmes begin at USD 4.80 per unit, with the final figure driven by the frame, the hardware specification and the leather grade. Autumn structured pieces sit above the entry band and holiday evening pieces often sit above them again because of the hardware tooling.
Should the leather grade change between seasons?
It can, but the change has to be planned. Moving to grained calf at 1.4-1.6 mm for a resort quarter is a sensible move, but it has to be paired with the 48 h salt-spray specification on the hardware, otherwise the assortment meets the market with the wrong finish.
How is a seasonal reorder audited?
A sample is pulled from the cartons and audited at AQL 2.5 (ISO 2859-1) against the approved first article rather than against a drawing. On a core shape that means the original sample, which is why holding it matters more than holding the paperwork.
What is the biggest risk in a seasonal calendar?
Underestimating the approval date. Bulk takes 35-50 days from an approved sample, and approval depends on a first article that most new silhouettes do not get right on the first round. Allowing one correction round is what keeps a calendar honest.
How do I plan a new silhouette inside a busy quarter?
Put it in spring. Spring pieces are the lightest in construction, sampling runs at 6-10 working days, and the quarter has the least capacity pressure. Introducing a new shape in autumn, where sampling already runs at 12-15 days, is the harder route.
People Also Ask
What is a seasonal planning calendar for handbags?
A backwards schedule from each delivery window: one week of tech pack finalisation, 6-10 working days of sampling, an allowance for one correction round, and 35-50 days of bulk production, set out for all four quarters.
How long before a season should I start sampling?
Sixty to seventy days before the cartons have to ship. Sampling itself is 6-10 working days, or 12-15 for a blocked frame, but the correction round and the tech pack finalisation are what most brands leave out of the calculation.
Which bag shapes suit which season?
Spring takes semi-structured bodies with a 6-8 cm gusset, autumn takes blocked frames at 26-30 cm with an 8-10 cm gusset, and holiday takes evening pieces at 18-20 cm with a 5-6 cm gusset. Resort carries the spring shapes over.
Should I change my bag shapes every season?
No. Keep one core shape frozen on a tolerance sheet and reorder it, and let colour and the surrounding pieces carry the seasonal change. Redrawing every quarter costs a sampling round each time and prevents a house style forming.
How do I avoid air freight on a seasonal order?
Plan on sixty to seventy days rather than on the 35-50 day bulk figure. The extra time covers sampling, one correction round and tech pack finalisation, and it is the difference between a calendar that holds and one that slips.
