This bra has great support for a strapless bra. I am a 38DD and finding something that both fits and works has been a nightmare. This stays up very well and gives great support. Now, of course, it is a strapless bra so it will never have the support that a regular bra has, but it comes pretty darn close. Pretty comfortable to wear too. One key thing is that it needs to feel rather tight around the chest to be able to support the weight of larger breasts. But it isn't uncomfortable. It works so well I may even wear this with shirts where my regular bra straps occasionally slip out.
