J.Crew to Athleta clothing size

The short answer

J.Crew 000 is Athleta XXS 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.

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

Tinted rows change label or sit between two sizes. 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.
