I was so worried it wouldnt fit, since Im extra curvy and top heavy, 42F and larger mid section. 38 waist. But I got the 6x and it worked well! I wore a black body suit underneath and it complimented so nicely. Great boning to pull you in. I just didn't like the laces in the back being flimsy ribbon! Lol! Kept thinking I was going to unravel!! But it lasted the whole day and night and looked pretty dang good for our St. Pattys Day fun!!!!
