Wanted to love it

I love the theory and the quality is outstanding, but it is just to small. It definitely doesn’t cover me like the pictures. Also, the return policy for anyone who has an APO address is non-existent., even though we have a normal USA post office and they sent it with no problem.

Non-Wire Bra Sizing

Non-Wire Bra Sizing Size Chart

* 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
