5’4, 155#, large breast (38DDD). I purchased size M. This fit nicely. Gave good boob coverage. Very good material that you can tell won’t mess up in the laundry process, but like most rompers it was definitely wedged in my booty all day

Cute Romper but runs slightly big especially in the chest area. I normally wear medium and ordered a Medium but it was a bit too big but not unflattering. I’m 5’ 145lbs w/ mom pooch and 34C and the boob and bottom was roomy. Should have gotten a small.
