    Great coverage with just the right fit!

    Haven’t yet worn this to the pool, but I can tell it’s going to be a favorite of mine this summer! Covers what I want covered, supports what I want supported, will go with lots of tops I already have.

    Exactly what I needed!

    I wish there was a little tummy control, but very happy with it! The skirt is a great length and there is good bum coverage.

    Nice swim skirt

    Very nice well made skirt but fits large. I did reorder to get a medium in lace of the large. Good coverage, the large was to long on me but the medium is the proper length for me. I am sn older woman and short. If your thinking about ordering it don't order a size up.

    Well worth the money!

    For the first time in a long time I felt comfortable and confident in this swim skirt. I walked around, swam, and sat poolside with no concern of leakage. I had no idea if these would work, and I'm very happy with them! I highly recommend this.
