    Jupe

    J'ai hâte de faire l'essai de cette superbe jupe de baignade, lors de mon prochain séjour dans le sud. Le model est vraiment beau et bien ajusté et très confortable.

    J'ai mis 3 étoiles pour l'efficacité, car je ne l'ai pas encore essayé a ce niveau.... À suivre

    Jupe

    Wow! Superbe produit, jupe fait vraiment bien. J'adore mon achat, alors j'en ait commandé une autre. Je ne peux pas noté l'efficacité encore, car je n'ai pas eu l'occasion.

    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.
