None of the padding. All the support.


Airy light and surprisingly strong — it’s not impossible, we made it.

    Finally

    Finally a bra that fits well, has support AND is comfortable. It's been a long slog trying other brands. Happy to have found my new favorite.

    great bra

    For somebody with a big cup size and smaller waistband size, it’s hard to find something that fits and is comfy. My mom told me that the bra was “very slimming” about 5 minutes after she saw me wearing it for the first time! great support and comfy material!
