so I was considering sizing up bc of the reviews but thank God I didn’t. I ordered my regular size and it fits perfect. It snatches you a little, but not crazy or uncomfortably. Lengthwise it’s perfect too. I’ll put it there that if you have bigger breasts you MIGHT need to size up because of it’s “snatching”. For reference I’m 156lbs, 5’4 and 36D and I ordered a M.
