J.Crew to Uniqlo clothing size

The short answer

J.Crew 000 is Uniqlo S by the two brands' own charts.

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

On 8 sizes the charts land two or more sizes from the same label. Brands do not measure the body the same way, so on those rows treat the chart answer and the same label as the two ends of a range.

Every J.Crew size read across to Uniqlo Japan sizing. US sizes on the left, Letter on the right.

Tinted rows change label or sit between two sizes. 4 sizes have no counterpart on the Uniqlo 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.
