I loved how it fit -ALMOST. Ordered a size 2 and I couldn’t believe the comfort and natural support until I noticed a bit of a pop up from the top of the bra at center. So I ordered a 3 - AND NOW MY LOVE IS STRONG AND CONSTANT!!! And my ‘girls’ are singing.

Light weight, secure and comfortable. Love the color, ordering more. Nice step up from a cheap bralette.

Really like this bra for under sweaters or loose-fitting collared shirts because it is so cloud-like and lightweight. I don’t wear it under tees because I’m not totally comfortable with nipping out (or showing the white lining), but if that doesn’t bother you, this would make an excellent everyday bra. My measurements are 36 C and that is exactly how the size 3 fits. It’s dreamy.

* 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
