I'm a 40dd  and it's fits perfect. This by far my favorite strapless bra. I've had this bra for 2 years and this went through multiple washes which it's still in excellent condition. I'm ordering the beige and black b\c I need extras in the different colors. Plus, for being big busted it holds the ladies up well. So, it has excellent support and it does not slip down. It holds well in place. It is under wire support. It is pretty comfortable. I'm actually going to order another white one too just in case. Oh, it also comes with straps if you don't want to wear it strapless and it has 3 hooks. At first I had to buy bra extenders b\c at the time I had more weight on me and I knew I was going to loose it. Since then I lost 40 lbs and now I don't have to use them anymore. I would definitely recommend buying this bra!! Remember I bought this bra in 2016 and these are recent pictures of the bra.
