J.Crew to Gap clothing size

The short answer

J.Crew 000 is Gap 00 by the two brands' own charts. 10 of 13 J.Crew sizes land on a different label at Gap.

Both brands publish the body bust each size is cut for, so every row matches a bust, not a letter or a number.

Every J.Crew size read across to Gap. US sizes on the left, US on the right.

Tinted rows change label or sit between two sizes. 2 sizes have no counterpart on the Gap chart. Read from the two charts only; no formula and no averaging.

What wearers say

Charts describe a garment, not a fit. We do not collect fit reports for this category yet, so this table is the two brands' own claims and nothing more.
