How to Plan Clothing Size Runs and Colorways for a First Order

1. Define the customer and fit before choosing a size ratio

Start by writing a buyer brief that describes who will wear the garment, how it should fit, and where it will sell. For a first menswear drop, distinguish between a fitted shirt, a regular sweatshirt, and an oversized T-shirt because the same size label can represent very different garment measurements. Specify the intended sales market, customer measurements where available, layering expectations, and the size range you intend to support. Use preorder data, customer surveys, previous relevant sales, or fit sessions as evidence. If you have no reliable history, describe the opening ratio as a test rather than presenting it as a proven market distribution.

Translate that customer profile into an approved measurement chart before deciding how many units to cut in each size. Ask the factory to review the base size, measurement points, tolerances, and grade rules, then evaluate the sample against the intended fit. For example, a provisional five-size ratio of S:M:L:XL:XXL at 1:2:3:3:1 converts a 100-piece order into 10, 20, 30, 30, and 10 pieces. This is an arithmetic example, not a universal menswear recommendation. A different audience may need substantially more small sizes or extended sizes. Confirm that each offered size serves a real customer need rather than copying another brand's labels.

2. Confirm how the 100 pcs MOQ can be allocated

Our MOQ is 100 pcs, but the allocation must be confirmed against the actual product brief. Ask whether the minimum applies per style and whether fabric sourcing, dyeing, printing, embroidery, or trims create additional minimums per color or design. Do not assume that five styles at 20 pieces each qualify simply because the purchase order totals 100 pieces. Likewise, confirm whether the factory can produce small quantities in the least common sizes without changing the commercial terms. Send one complete allocation sheet listing style code, fabric, color, size, quantity, and decoration details so the production team can check feasibility and quote the same specification you intend to order.

If the factory approves a 100-piece split across two colors for one style, a 70-piece core color and a 30-piece secondary color could use the same illustrative 1:2:3:3:1 size ratio. The core color would receive S 7, M 14, L 21, XL 21, and XXL 7; the secondary color would receive S 3, M 6, L 9, XL 9, and XXL 3. Each color total and the combined total are exact. This split is conditional on accepted color minimums, not a promise that every fabric or process supports it. When ratios produce fractions, round deliberately and reconcile the final matrix before purchase order approval.

3. Limit colorways to protect first-drop inventory

Every additional color multiplies the number of stock combinations you must manage. One style in five sizes and two colors creates 10 size-color combinations; the same style in five colors creates 25. Across 100 pieces, that changes the average depth from 10 units to four units per combination, even before you weight popular sizes more heavily. Thin inventory can sell out in a key size while leaving cash tied up in less wanted combinations. For a first drop, consider one core color or two colors with distinct demand evidence. The objective is not to make the range look small, but to give the most credible combinations enough stock to test demand meaningfully.

Choose colors using evidence from your audience and product positioning rather than assuming one neutral shade is always safest. A workwear-oriented customer, a gym audience, and a fashion-led buyer may respond differently to the same garment. Compare expressions of interest with stronger signals such as paid preorders, while recognizing that either can be affected by campaign reach and presentation. Review the actual fabric color reference and relevant print or embroidery sample before committing. Different colors may involve separate material availability, dyeing requirements, or decoration contrast checks. Ask the factory to identify these constraints early so a secondary color does not unexpectedly change the cost or production plan for the entire order.

4. Approve the matrix and use sales to improve the next run

Before production, issue a version-controlled order matrix and make it the quantity reference for the purchase order, packing instructions, and inspection checks. Record totals by size, totals by color, and the overall piece count, then check that all three reconcile. Include the approved measurement chart, color references, labels, packaging requirements, and decoration placement in the same handover package. Samples take approximately 7 days once the brief and materials are confirmed. That estimate does not include an undefined period of brief development, material selection, or revisions. Bulk timing depends on quantity and should be confirmed separately after the product specification and allocation are settled, rather than inferred from the sample timeline.

Once the first order launches, review performance at the size-color level instead of relying only on total revenue. Track units sold, available stock, time in stock, exchanges, returns, and the reasons customers give for fit problems. A sold-out size may have unmet demand, while a slow size may simply have received less exposure or arrived later. Avoid treating those observations as equally reliable. Record stockout dates and requests for unavailable sizes to improve your next allocation. Share the revised matrix with the factory before committing to a reorder, because changed color proportions or new fabrics may alter feasibility. Keep the original ratio as a baseline so each production cycle produces a measurable planning lesson.
