* 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

Zero complaints about this bra the comfort and support is wonderful. I was hesitant at first that I was feeling a little droopy, but then I was able to adjust the straps and I instantly had the lift I needed.. I’m shocked because I only wear padded lift bras. This is exactly what I need.! I definitely wanna buy this again and other colors!

So comfortable, barely there feel, can wear this all day and not feel the need to rip my bra off after the end of a long day at work

This is exactly the bra I was looking for… except the material and the band are so uncomfortable. I bought two and thought I loved them at first so removed the tags on both but after wearing, it’s a lot of money down drain. Wish they could make this in a softer material with the top part in the back a little lower so it isn’t visible under shirts.

Really great for V-necks and racerback tank tops. After trying a size 2 and not filling out the cup completely, size 1 was the way to go. I typically wear a 34 A/B size bra, depending on the brand.
