* 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.

Sieve Non-Wire Bra in Black
Rated 4 out of 5 stars
Surprisingly supportive
I was impressed with this bra. For reference, I wear a 36D and got the 3+ size for additional support. While it doesn't look quite as chic or minimalistic as the original, the straps are comfortable, the band is supportive, and the coverage is a lot better than what I remember from the original fit. My only complaint is that my boobs tend to get a little squished towards the middle, especially when I'm wearing a backpack, and create a weird shape. But for weekend lounging and hot days where I don't want to do anything, this is a pretty decent wireless bra.

So comfortable
I've really struggled to find comfortable bras in my life since I'm apparently an unusual size, but the size 2 fits perfectly and the fabric feels great on my skin. Plus the black mesh is just super sexy. The straps are a nice thickness where they sit really nicely too and don't dig in. It's a perfect bra!

Very comfortable with light support!
I am pleased with the comfort and light amount of support. My only complaint is that the site’s size chart is a bit on the generous side. I followed it to a tee and I think I could have sized down one size.
