* 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 this bra. Another reviewer said it’s magic and I agree! When I opened up the package I thought there’s no way this is going fit me but to my delight it fits beautifully. It looks so great, so sexy. I feel so good, supported. I just can’t get over what a fantastic bra this is! I’ve already ordered another one.

I would recommend sizing up on your band! I typically wear a 34A and so purchased a size 1. While the cups fit well, the band cuts in more than any of my other bras. Unfortunately that means this ended up being an expensive purchase that I never wear!

My brain forgot that I was wearing it from the first moments on. It looks natural. It disappears from under a racer tank top. There are no straps to slip down over my shoulders. This bra satisfies every requirement that I have from a bra with no discomfort. .
