    Many other bras out there for this price and they charged shipping + tax. Not a good deal for a minimal bra with no support. Not Happy!

    Love but…

    Love these bras - I’m a bit nervous though because I’ve had one for about three weeks and noticing some stretching already happening - I bought another so I can switch them out more often - we shall see

    So comfortable

    This was super comfortable and supportive. I have newer implants and this bra felt secure and high quality. Fit like a glove. Please make more in the DDD sizes!
