    nice coverage

    Suits the purpose of extra coverage when I have pool guests, but the overall style could be more "fun" and offered in more colours.

    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.

    Nice Essentials Skirt

    Loved this! Doubles as a cover up so I seldom had to carry extra when on a vacation. Looking to buy another!

    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 But

    As my previous review of this product stated that the skirt seemed way to long for me, so i ordered a medium in place of the large. This was very easy to do and the new one came so fast. I love the skirt of this product, nice fit and great material. I am disappointed with the under liner, just not made right. I would prefer that it go down further on your behind, it also felt loose to me. I have the perfect solution, I am thinking maybe I can cut the liner out and wear my Leakproof Swim Short under the skirt. This would give me way more confidence as I feel if the skirt blew up I would be self conscious. Maybe you could start making skirts to just pull over the Bottoms. I would recommend this product but the liner needs to be made better.

    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.

    Nice fit, cute swim skirt

    I haven't used it as a period swimwear piece yet (haven't needed to) but it is a nice swim skirt, great length, fit and colour. I only gave it a 4 because I cannot comment on the "leakproof" part just yet!
