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 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
  • A caramel-y sunrise desert sands affogato tone
  • 79% Cotton, 21% Elastane is breathable and flexible
  • Wash on delicates/cold, tumble dry low

Terrible

Looks smooth and neaten the photo but it’s just plain cotton. Tried the white and the band folded while wearing and the cup fabric pilled after one wear. I bought it in buff and black and wish I could exchange them for the glacé instead but they denied my return.

Super comfortable and flattering

It’s so nice to find bras that are comfortable and still sexy without being overly frilly. Love this bra!

Comfy at first but not all day

I have been on a mission to find a really comfy and sexy bra. I wanted to love this bra, but late in the day the strap starts bothering me. I have it on the last hook but it feels too tight.

Non-Wire Bra Sizing

Non-Wire Bra Sizing Size Chart

* Non-wire bra sizing can vary by preference and if you're toward the top of a size range and prefer more coverage, you may want to size up. For styles available in + sizes (designed with additional support details for our larger cup customers), we find DD's can be on the cusp - if you prefer more coverage and support, we suggest the + bra equivalent for your band size.
