Flat-front and pleated chinos, cargos, cropped and tailored bottoms, where the grade across the size set decides the return rate.
Bottoms are bought in a size curve, so a block that works beautifully on the sample size and drifts at the ends of the range will still generate returns across half the order.
We approve bottoms across the graded set rather than on one size, confirm fabric shrinkage before the pattern is finalised, and check rise, thigh and hem measurements lot by lot - the three places where drift shows up first.

Bulk measurements checked against the graded spec across sizes and lots, not just on the first output.
Fabric shrinkage tested before pattern finalisation so washed measurements stay in tolerance.
Check and stripe matching specified, costed and inspected — it drives both fabric consumption and perceived quality.
Stitch density, seam pucker, collar roll and final pressing assessed at inline stage while correction is possible.
Send a reference garment or a tech pack and we will come back with the factory, the fabric route and a costing.
