Fit

  • Size Chart
  • Use this as a guide. Preference is a huge factor — the benefit of a non-wire is they're super flexible, so you will likely fit in more than one size. Like a looser band? Size up! Like less coverage? Size down! Still unsure? Try two sizes :)
  • *Note, our Sieve Non-Wire doesn't have the same wide band as our Silky. As a result, it'll likely feel snug the first few wears. Don't fret — it'll stretch a bit with time.

  • Made from a sheer Belgian power micromesh — nipples are visible
  • A caramel-y sunrise desert sands affogato tone

Obsessed!

I’m crazy about this bra. As a small breasted woman, I’ve never worn a sheer no padding bra in my life without being self conscious. This gives comfort and smooth lines. I already bought another, told all my friends to get it, and am ditching my old bras for good! Thank you!

This is the one!

I have been searching a long time for a comfortable bra & finally I found it! I will be tossing all my other bras because I know I will only wear this one. Admittedly, like others said, I was thinking the fabric would be softer & when I first put it on I wasn’t 100% sold, but I a quickly realized how comfortable it was. I wore it all day & actually forgot I had it on!

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
