* 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

It’s built nicely, but the material surprisingly rough. Less like butter, more like sandpaper. I have mixed feelings about this bra. It’s not bad, but it’s not something that I eager to wear every day. Considering the price, I expected more.

I only wish my size came in more colors. Black and navy seem to always be out of stock or are not carried in the 5+ size.
Other then that, I really love this bra.
