Comfy and Sexy!

I love my white Sieve non-wire bra! I have black too. I really like the extra support on the sides and wider straps. Wear these every day and feel confident and sexy.

Love

I really love these. I have 5! I really would love more size selection as I need a 40 band and a c/d cup. I buy the size one to get front coverage but really need a smaller band.

Fabulous bra

I am a 34D and the size 3 is a perfect fit. I bought a white one last week and I loved it so much I bought the slate to have a darker color too. It surprisingly holds me in such a comfortable way. It breaths great too. My husband loves the see thru material- Super sexy.

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
