I am between 5'0 and 5'1, I'm 200lbs and a 40D in a regular bra. I ordered a 40D and I think I should have sized up to the 40DD. It shrank a little in the wash, so now it's a workout and a half to put it on as opposed to just a regular workout when I first got it in the mail. However, that could do more with the fact that I also struggle because I can't reach behind myself to fasten a bra the normal way, so I always fasten in the front first, the turn it around to put it on (and that goes for anything with a hook or string I need to fasten in the back) it has hooks on the crotch area, and it was a struggle for me to get them on and off properly, so it made it tough to go to the bathroom. Very good for tummy control I think. It may not suck everything in (I think only a corset or waist trainer can do that), but it brought in my lower tummy pouch and smoothed every thing out so I was able to wear this and fit into my clothes and bridesmaid dress better. I had originally bought this to help me fit better into my bridesmaid dress better, since I first got the dress it was a little tight, but the shapewear did its job well enough for me.
