Goldwin to Boden clothing size

The short answer

Goldwin 1 is Boden 2 by the two brands' own charts. 4 of 5 Goldwin sizes land on a different label at Boden.

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

Every Goldwin Japan sizing size read across to Boden. US sizes on the left, US 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.
