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

  • Size Chart

Cute, but could be a better fit.

I'm a 36DD and I ordered the 5 according to the size chart. It fits okay, especially in the cup size, and is a beautiful color. However, despite me getting the largest size, the band is not super comfortable especially after a few hours of wear, and it folds so that it cuts into my skin and/or bunches up under my boobs. I am not sure if I had gotten the + size if that is just for the cups or if that would have helped. I would go with that if I were ever to try it again. The bralette may just be a better fit for people with a smaller band size - I'm not sure. Overall, it's still cute enough that I kept it and I do still wear it, so it's not terrible. But for the price, I want things to fit, feel, & look great.
