Sandro to Farm Rio clothing size

The short answer

Sandro 38 is Farm Rio 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.

Every Sandro size read across to Farm Rio. FR 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.
