* 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 love my other triangle bras in the sieve fabric and have been wanting a racer back for a while. The spark adds some fun shimmer! A great addition to my other Negative bras

I love the fit and fabric, which is see thru with no padding. It’s a super hot sexy look and I just wear pasties, when needed, to cover my nips! I bought this is 2 other colors and love the racer back with front closure for all my racer back tanks/tops.

I ordered the Sieve Non-Wire Bra in the same size and it fits great. This style ran smaller - wish I sized up.
