How do you handle size grading across a full Custom Bottoms range?

Size grading across a full range

Grading means applying consistent increments between sizes so the fit stays right as the size changes. We agree the base size and the increments with you, then apply them across the whole range rather than scaling a single size by eye.

In practice the base size is approved first, because the increments follow from a fit you are happy with. Once the base is confirmed, the pattern is graded across the range and the result is checked on a graded sample before bulk production.

For extended or plus sizes, grading is handled with extra care, because increments that work in the middle of a range often need adjusting at the extremes. Testing one extended size early in development is much cheaper than correcting it after bulk.

The graded chart is documented, so a reorder or a new colourway follows the same fit rather than being re-graded, which keeps bottoms consistent between production runs.

Send your target size range and base size and we will confirm the grading approach for your order.
