* 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

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.

It looks fantastic. Good for racerback shirts. Sits very high on the neck of the neck.

I love the look of it, but between it running small and the mesh material being harsh on my skin, this was an expensive bra that I'll never wear again. It's too bad because I would probably want to wear it everyday if it was the proper size and if the band was made out of a more gentle fabric.
I wear a 34B and typically wear a size Medium. I bought a size 2, but wish I had bought a size 3. I'm even wondering if a size 4 would have been best. I loved the way it looked when I put it on. I instantly cut the tags off. Within a few hours it was digging into my sides. By the time I took it off that evening, the marks it left on my body were so deep that they remained throughout the next day.
I wish the return policy was a bit more user friendly.

Then I could show how the color of this bra is lighter in person, whether in bright light or sunlight. I really wanted to like this bra, but the shade of pink just doesn't work for my skin tone or personality. Also, the size 2 was really comfortable all around, however my breasts must not fill it out completely, as there were weird lines/ wrinkles above my nipples on both sides. I ordered a size 1 in a different color to solve this issue, hopefully.
