COS CLEAN CUT REGULAR T-SHIRT in Grey Marl Size Small BRAND NEW - I took the tags off before trying it on - which was a mistake! I usually wear a small or medium in COS but in my opinion this color fits like an XS or a smaller size small. I love the clean cut shirts from COS and I have the white one in small which fits great, but this one in grey is too snug for my liking.
