    The fabric itself is quite good really comfortable but one thing i want to point out is the straps are sewn on quite badly there are loose strings and the width of the straps are very thin for ppl with broader shoulders not recommended. Also i wish they made the straps wider. Without the loose strings. The sewing is not great

    A fantastic one piece swimsuit

    I love this suit so much that I may just have to go back and purchase the black one! I'm usually a medium but, because I'm long waisted, went with the large and it fits perfectly.

    attractive suit

    This suit is a great one piece with simple design. The blue color (the one we got) is very attractive. We need a smaller size as the suit does not fit snuggly. When it does, I'm sure it will work well for it's needs.

    Great swimsuit

    Love the fit! It’s hard to get a long torso in a swimsuit any more! I love Knix fabric, so silky smooth!
