* 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

I heard Tyra Banks say that natural big breast need overnight support to age better and I’ve worn some sort of sports bra for the last 10 years. Now I can’t sleep without it and I do think it’s made a huge difference in the gravitational department! Purchased a few of these a year ago for sleeping as I need serious support and they work amazing! I’ve tried every thing out there and this is the only bra that works for me! Thank you Negative!!!

This is a really beautiful bra. I wore this bra for a yoga class without anything else on top over it, and the men in the class were staring at my breasts all day. The bra shows off my breasts really nicely and makes my nipples look so sexy.
