Athleta to Nike clothing size

The short answer

Athleta XXS is Nike XS by the two brands' own charts. 4 of 8 Athleta sizes land on a different label at Nike.

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

Every Athleta size read across to Nike. Letter sizes on the left, Letter on the right.

Tinted rows change label or sit between two sizes. 1 sizes have no counterpart on the Nike 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.
