Lacoste to Marks & Spencer size
The short answer
Lacoste 2XL is Marks & Spencer XXL by the two brands' own charts. 4 of 9 Lacoste sizes land on a different label at Marks & Spencer.
Both brands publish the body chest each size is cut for, so every row matches a chest, not a letter.

What wearers say
