Mostly good

The color is really nice. The fit is good, which is relief, since I have trouble finding non-wire bras with small bands and large cups. And the shape is flattering.

The only reason I didn’t give it a 5 is that the band feels kind of scratchy. Hoping it softens up after some use.

The Sieve is the best bra ever.

Only one thing could make this bra better=racerback. I put a tiny catch on all my Sieves to turn them into racerbacks and it works pretty good. These are my go to daily bras. They are SO frikin' comfortable and I just love them. Durable as heck, stay put, no band rolling, etc. I've had one for years that looks as good as the day I bought it (and I'm very rough on them with my active lifestyle). This is the only bra that fits my wide chest/small boobs that actually looks like a sexy bra and not a workout tube. I'm 5'8" 155 and usually get 36A or M; I get size 3, always fits perfectly on the 2nd clasp.

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
