28”-30” waist (there’s also some stretch) Bust is adjustable because of open back. There are built in cups. It’s LONG, so if you’re short like me, expect to alter. I didn’t end up wearing this and it has not been washed or altered to my knowledge. Reposhing this item I purchased from @sophisticatedw. Loved it, but ready to rotate for something new. Questions?
