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.

Fabric + Care

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

Disappointed

This bra after shipping was $70 and it just smashes my boobs with no real support like a crappy sports bra I could of gotten for $20 at Walmart. Maybe be comfortable to wear around the house but doesn’t make my bust flattering in clothes. Also runs small, I’m 40C so the XXL I still have to put it on the last clasp. Not worth the money. Also in this review I’m trying to choose what size I got and 5 isn’t even a option. Stupid..
