Steady core, peaked edges
Read any year of intimates demand and two layers separate out. The core - black, white and skin-tone basics in everyday styles - turns over all year with modest movement. Around it, peaks form where the calendar gives people a reason to buy: gifting weeks, warmer months that shift demand toward lighter fabrics and strapless or bralette styles, and cold months that lift thermal and seamless layers. Neither layer is guessable from the other. A brand that staffs and buys for the core alone meets the peaks out of stock; a brand that buys peaks like core ties up capital in shades nobody wants in March. The planning job is to treat them as two budgets with different rules, and the color tiering in the note on bra color range planning is the same idea applied to the palette.
A season map for planning
The map below is a northern-hemisphere planning frame, and every window in it is set by the brand calendar rather than by the factory calendar.
| Window | Demand driver | Stock action |
|---|---|---|
| Mid-February | Gifting and occasion colorways | Seasonal buy lands in January; peak backup on sets |
| Spring into summer | Lighter fabrics, strapless and bralette styles | Build depth from March; watch strapless sizes first |
| Fourth quarter | Gifting, sets and bundles | Deepest stock of the year; bundles packed in advance |
| Cold months | Thermal and seamless base layers | Source from the thermal-strong clusters; land by October |
Cold-month lines deserve a sourcing note of their own. Thermal and seamless innerwear concentrate in the Yiwu cluster, which pairs those categories with a broad multi-category supply base, while the southern clusters stay bra- and seamless-centric; the cluster map sets out who makes what. Matching the cluster to the season avoids paying a learning curve to a plant whose machine park is built for a different product.
Two habits keep the map honest. First, each window gets its own review after the season - what sold, what hung, which sizes broke first - so next year buys on record instead of memory. Second, peak windows are where bundle formats earn their keep, because a packed set moves more units per order than a single style; the note on bundle ideas collects the formats.
Lead times set the calendar
The reference ranges across the category run as follows. Sampling is 7-15 days on a catalog model, 15-25 days on a branded sample and 20-35 days where a custom print or lace has to be developed. Bulk runs 30-45 days on catalog models, 35-50 days on branded programs, and a first ODM order runs 60-90 days because patterns and molds are being built, not just sewn. Ocean freight adds 15-25 days to the US West Coast and 30-45 days to Europe; express courier runs 5-8 days where a gap is small enough to bridge by air, and intimates move by air without restriction since they carry no batteries or liquids.
Work an example backwards and the calendar writes itself. A gifting set that must be in the warehouse by early November needs bulk production finished by late September on a branded program, which puts the seal sample in August, which puts the specification and palette decision in July. A first ODM program with the same landing date starts in spring. The desk builds this timeline into every quote, and the freight detail sits on the logistics page with the note on ocean freight for apparel. Peak windows also tighten freight: vessel space around the fourth quarter books out early, so the desk reserves space when bulk starts rather than when it ends.
Cash and containers: how a peak order ships
Peak orders also concentrate freight. A gifting season buy often fills a container on its own, and the difference between a full container load and a consolidated less-than-container load changes both the freight spend per unit and the port handling time. The desk consolidates orders across programs when volumes allow, which is routine work for a sourcing desk and awkward for a single brand shipping alone; the sourcing agent page describes the consolidation route. Carton discipline matters as much as container choice: intimates are light but bulky for their weight, so carton cube fills before weight does, and the pack-out decided at the packaging stage determines how much of the container the program actually buys. Distributor programs that ship mixed color tiers should agree the carton mix before bulk, so the warehouse receives tiers it can put away without re-packing. None of this is glamorous, and all of it lands in the cost of holding stock through a peak.
Depth versus breadth by channel
The same season asks different stock shapes from different channels. Distributors and wholesalers need depth inside a disciplined color ladder, because their customers are retailers who re-order the same shades; the distributor playbook leans on tiers for exactly that reason. DTC brands run the opposite risk profile: breadth on display, small lots behind it, and reorder speed doing the work that depth would otherwise do. Marketplace sellers hold many SKUs with thin stock per SKU, so their season plan is really a restock schedule per listing, and a stock-out costs listing rank, not just sales. Retail chains buy shelf-ready programs against fixed planogram dates, which makes the landing date contractual rather than aspirational. One category, four stock shapes - which is why the desk asks about channel before quantities.
Reorder discipline: a sequence
- Split the range into core and peak lines, with separate budgets and separate reorder rules.
- Set a reorder point on each core color from observed weekly movement, not from gut feel.
- Lock peak orders to the backwards calendar: palette decision, seal sample, bulk, freight, landing.
- Keep retained swatches per color per lot, so every reorder matches the shade the brand launched.
- Review each peak window after it closes, and fold the record into next season's buy.
