    Amazing

    Unbelievably comfortable, super cute and the straps stay on my shoulders! There are no other non-racerback bras that stay on my shoulders this well. Sizing was spot on - I love that there are no measurements, you're a number 1-5. LOVE!

    Love the Sieve Triangle bra.

    The reduced cut is both comfortable and sensual. I’m a size 38C, sized up to a 5, glad I did.

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
