J.Crew to Next size

The short answer

J.Crew XXL is Next 2XL by the two brands' own charts. 2 of 7 J.Crew sizes land on a different label at Next.

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

Every J.Crew size read across to Next. Letter 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.
