* 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 really love this racer back bra - it is beautiful and comfortable and has such a subtle touch. It’s great to have a racer back that I can wear with tshirts

The first bra was too small overall so I exchanged it for one size larger. The band was still too tight and the cups were too big. No fit for me. The second bra also had a manufacturing defect that left a twist in one strap so it would not lay flat.
