    What is the opposite of soft?

    It’s built nicely, but the material surprisingly rough. Less like butter, more like sandpaper. I have mixed feelings about this bra. It’s not bad, but it’s not something that I eager to wear every day. Considering the price, I expected more.

    I love these bras

    I only wish my size came in more colors. Black and navy seem to always be out of stock or are not carried in the 5+ size.

    Other then that, I really love this bra.

    Purchased for wife, she loves it.

    She loves the feel and fabric. I was nervous about the fit, she's 38DDD, the 5+ fits perfect. We were both pleasantly surprised by the quality and fabric.
