Period Pants Size Grading for Cross-Border Private Label Programs

Cross-border period pants programs often fail at the size file before they fail at production. A buyer may approve the product structure, but if the size grading, size ratio and pack route are unclear, the final goods can become difficult to sell, sort and reorder.

Start With the Market Body Range

The size route should match the target market rather than a generic factory chart. Buyers should compare waist, hip, rise and coverage expectations before deciding whether the order needs M to XL, M to XXL or a broader size range.

Separate Sample Fit From Size Ratio

A comfortable sample in one size does not decide the full size ratio. The buyer still needs a commercial size plan based on channel, customer group and reorder expectation. This should be recorded before carton planning begins.

Match Size Labels With Pack Design

Retail packaging should make the size clear for warehouse and shelf teams. If one carton contains several sizes, the outer mark should explain the ratio clearly enough for receiving and stock control.

Keep One Baseline for Repeat Orders

Once the first order is approved, the size chart, pack count and carton ratio should stay in the repeat-order folder. Any change should be treated as a new version, not a silent edit.

Use Size Grading as a Buyer Control File

A size file is not only a design document. It is a purchasing control file that protects sample review, quotation, carton mark and reorder planning.

OEM Buyer FAQ

Should these records be prepared before quotation?

Yes. A clear record helps the factory quote from the same product route, pack route and approval version that the buyer expects.

Can one approved sample replace the written file?

No. The sample, photos, specification, artwork and carton notes should stay together so the production handover is traceable.

What should buyers send first?

Send the target market, product category, sample photos, pack count, size route, artwork status and expected order quantity range.
