* Non-wire bra sizing can vary by preference and if you're toward the top of a size range and prefer more coverage, you may want to size up. For styles available in + sizes (designed with additional support details for our larger cup customers), we find DD's can be on the cusp - if you prefer more coverage and support, we suggest the + bra equivalent for your band size.
Btw, the size nomenclature has changed for Bra Tops. Here's the conversion:
XS=0, S=1, M=2, L=3, XL=4, XXL=5

My favorite bra. I am supported and don't feel like I am wearing anything, even in the SC heat. That is saying a lot for someone who is a DD.

Nothing more to add except that this IS the perfect bra. Only problem is that now I have to get rid of everything else bc since ordering this and the Whipped non wire and the Sieve Bra top, I haven’t reached for anything else. If you’re on the fence, JUST GET IT.

Incredibly comfortable, when I’m wearing my other bras I really notice how much better the comfort is here. I do find it slightly flattening but am looking forward to having for the summer months. I do wish negative offered an even slightly lined wireless option.

My expectations were low and I was honestly so impressed the first time I tried this bra on. It's comfortable, supportive, and my nipples remain hidden under most tops (white, being the exception). Highly recommend!
