Pretty, but, unfortunately, it is small. I contacted them about it and it seemed they encouraged giving it a try I should have returned it.

I love the fit and style of the sieve triangle bra, but the white trim was too visible under all my white tanks and t-shirts for summer, so it was returned.

I have worn this bra a couple times now. It is very flattering and I enjoy to wear it. It is comfortable when sitting and being active (walking long distances.) The band does not roll or dig in. The navy color still somewhat disguises the nipples. I am a 34C and a size 2 fits great.

* 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
