DESCENTE to Sandro clothing size

The short answer

DESCENTE O is Sandro 38 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 DESCENTE Japan sizing size read across to Sandro. Letter sizes on the left, FR 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.
