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 :)
  • Adjustable straps and hook & eye closure in the back
  • *Note, our Sieve Triangle Bra is an intentionally lower coverage in both the cups and the sides. Wide plush elastic band is extremely adaptable.

Fabric + Care

Perfection!

I am thrilled with the look and fit of my new Sieve Triangle Bra in Buff! It is very comfortable and gives me a soft, natural look. I am definitely going to order another one.

Tiny triangles

Like the fabric and style but the coverage is minimal. I have many sieve non wire bras and find them quite comfortable but wanted something that gave the look of separation. This bra does that but occasionally the coverage slides and a nipple comes hazardously close to escaping. Might be good for women whose nipples point more towards the outside?

Love the fit!

I absolutely love the fit and feel of this bra. I was looking for a bra without wires that still gives support. It gives great shape and support.
