* 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

Love it, can't feel it at all, such an upgrade from underwire. Also looks great and doesn't flatten out your boobs at all.

Solid performance for me at first wear, I wouldn’t go jogging in her but I feel really secure (I typically do not wear underwire bras). My husband was a bit shocked at the sheerness but I love it.
