Very comfortable and great with racerback tanks. I do wish there was a tiny bit more coverage on top of breasts.

Ordered this for my wife. She indicated that she loved the color and for the most part the fit. Indicated that with her body frame these types of bras do not fit her well. While we returned this to get something she’ll wear more often she had nothing but good feedback otherwise.

* 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
