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.

Sturdy and comfortable

I usually wear a 40B, and purchased this in a size 3. It's a little compressive currently, but I am losing weight and this is more than I would usually spend on a bra, so I wanted to err on the smaller side. It is quite comfortable, and the construction feels like good quality fabric and trim. Looking forward to trying other styles.

Amazing

I've been looking for a wireless bra that was still cute with a smaller band but larger bust. This is it. Will definitely be ordering a few more! 10/10 recommend. Their sizing tool was perfect as well

Sieve non wire

I just ordered 5 more. It’s my best bra. Size 38B, ordered size 3, shapes naturally, feels sleek. Love the slim band—the triangle bra’s was wider with less give, and I would have had to size up (but I’m unsure about whether to get a 4 or a 5, based on the charts)
