* 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

I was so impressed with this bra! As someone with a small band large cup size (30DD) who spent many years nursing, finding a supportive wireless bra can be challenging. The Sieve bra is so comfortable and supportive. Highly recommend!

A bit pricey but this is such a well made bra. I have saggier 32DD breasts despite being young and not having kids, so usually bralettes do not give me any lift but this is so sexy and tasteful. I love that it’s adjustable

She absolutely loved this bra. She normally takes bras off as soon as she can due to discomfort and left THIS one on all day.
