  • 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.

Love it!

The best non-wire triangle bra yet! Finally one deep and low enough to not poke out from most dresses and tank tops, yet supportive and no awful padding! Nice work!

Enthusiastic Buyer

I never really write reviews, but I had researched a lot of different companies for months. When I found Negative, I was drawn to their minimalist/sheer looks they have to offer. I love the material, the deep cut, the comfort, and how beautiful this bra makes me feel. Glad to support a female-owned business.

Sexy

Sexy, but a little to tight. I will buy again, but the larger size. It's nice to wear in small doses. Not all day. I love the soft tank!
