My new favorite bra

The mesh material is perfect - wildly comfortable and flattering, subtly and understatedly sexy. I definitely want to get this in more colors! Only thing is I wish there was a size chart with bust and underbust measurements in addition to standard bra sizing - my body has changed recently and I have no idea what size I should be wearing anymore, so I kinda guessed and luckily it fits perfectly. It's hard enough getting a good fit with a bra, especially when shopping online, and showing measurements would really help. (In case this helps anyone: I previously wore a 32B, but now I think I'm somewhere in between a 30C and 30D - got a size 1 in Negative sizing.)

Comfortable

I have purchased 2 bras within 2 weeks and I must say I love them. I usually don't wear bras because they are really uncomfortable but every now and than I want something to hold the girls out without the wire and discomfort and these are it!!!

Non-Wire Bra Sizing

Non-Wire Bra Sizing Size Chart

* 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
