    Sieve Bras

    I ordered this bra as well as the Sieve Non-Wire Bra in Buff + White. I enjoy both, especially the light but strong mesh material, but I prefer the bralette style non-wire bra. This bra top is very much a sports bra style, which is nice, but less versatile for my closet. Also, the wide band tends to fold. I appreciate the wider straps--very comfortable. I am a B cup.

    My new favorite bra!

    It so so comfy and so flattering at the same time! I don’t want to take it off. Will order it in more colors!

    Super comfortable!

    I love that I don't need to adjust any straps; it just perfectly fits on me.

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
