    The most comfortable bra

    My daughter tried on one of the bras I had bought for myself and she loved it so much that I bought a few for her. The Harper Wilde bras are by far her most favorite bras! They are so comfortable and soft and the straps are so easy to adjust. A huge win!

    Amazing

    I didn't realize it's got some padding like a push-up, but it looks great. I've worn it a couple times and didn't need to pull it up at all. Pretty comfortable.

    Best Bra Ever!

    I have tried so many bras trying to find one that fit and was comfortable. This was it! I now have 4 and couldn’t be happier. I forget I’m wearing a bar half the time and somehow every shirt fits and looks better!
