    Nice

    These are nice but not as covering as I had hoped. Very comfortable though

    Sizing is off and very show!

    I always buy a size medium in Knix and love the comfort and no show. It’s my first time buying the bikinis, and these are so tight and very very show under cloths.

    I’m so disappointed especially given how much they cost.

    Recommend sizing up for these ones. Not sure why the sizing would be different…. What’s going on Knix!?

    Comfortable everyday underwear

    Easy and comfortable to wear. I’m wearing Essential for the first time instead of Leakproof and some sweat does break through quite easily. I will purchase dark colours going forward so it’s less noticeable for me. The fit is nice.

    Ok.

    I had heard great things so expectations were high. Didn’t fit quite as cozy as I’d hoped.

    Loved the fabric! I am not sure if I should have gotten and XS+ or an S due to my rounder backside. Iverall good fit, no riding up and super seamless!
