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.

Feels like wearing nothing

Light weight, see thru, doesn’t ride up. All things I was concerned about but not any more!

perfect for "new" mom

Are you still a new mom if your kid is a toddler? After living in their underwire bras pre-pregnancy, the sieve non-wire was my first non-maternity bra purchased. It honestly made me feel sexy again. It's a treat to wear a non-wire bra that is actually supportive without having padding or gigantic straps (why??). Totally worth every penny.
