None of the padding. All the support.


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

    Very comfortable pretty bra

    It is a very nice comfortable bra. I have been looking for new bras for awhile and think I found the right brand. I would love it if Negative would make a cotton version.

    Pleased with order

    Like this a lot, it feels very durable and breathable. The underwire is a bit uncomfortable, but that comes with the territory with underwire in general. Will be ordering more styles from negative in the future

    Bra Hunt is Over

    I have been on the hunt for a nude bra that fits well and can’t be seen under shirts. This is the one. It’s pricey but worth it. Buying multiple colors now.
