* 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 the racer back style, the mesh fabric and the front opening on this bra.
I hate the fact that the closure on the front is itchy and uncomfortable, they cost about $30 more then I would expect them to based on the fabric/quality and construction.
Also, importantly they do not fit (me) very well, leading to a kind of double-boob situation which is not so cute.
Gonna give them a couple of more wears and see if they improve.

Very comfortable. The edges sometimes roll a bit. Wish I could wear on its own all the time, but with certain tops, I need to wear nipple covers with the bra for modesty. I originally got size 0 but it was too tight and proportionally too small. Size 1 gave better cup coverage.

I had high hopes for this bra because it's flattering and made with quality materials. Unfortunately, the design fell short for me. The top of the T-strap sits too high—almost at my neck—and is visible with every racerback tank I tried. The elastic bottom band feels rigid and uncomfortable; a softer, more flexible band would make a big difference. For a non-underwire bra, I was expecting more comfort, especially for lounging, but it just didn’t work out. I wear a 34B and went with a size 2 based on reviews saying it runs small, but it fits nearly the same as the size 1s I already own.
