* 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 wore this bra all day at a music festival in 90 degree heat. I wasn't uncomfortable for one minute. My only complaint is that I'm at 32DDD and the band on the recommended size is a bit big. I'll play around with sizing on my next order.

literally makes me feel so hot and it's so comfortable! i bought one, wore it once, and then bought 2 more. i got a size 2 and it does sort of compress my chest a lil so i look a bit smaller than usual but i love the sheer mesh, it's just so cute to have my nipples + piercings show through.
