I'm a size 14, breastfeeding, size 36C - the fit was really flattering on the tummy down, but was quite revealing up top. The straps don't adjust tighter, only looser so it wasn't possible to make the top part smaller. I ended up wearing a black bra under just for extra support and because the straps often fell down.
I got lots of compliments, and it's a well made jumpsuit, I think maybe just for a smaller size body and smaller size bust.
