    Love the Thigh Saver

    The LeakProof Contour Thigh Saver is great for wearing under dresses and skirts. Finally able to find light shapewear that doesn't roll down. Very comfortable and fits true to size.

    I'm in love, for real!

    I absolutely love these Thigh Savers. They are incredibly comfortable, don't roll down at the legs or waist, and are almost invisible even under my tightest dresses. I love the comfort of wearing them without underwear. I honestly don't think I could ever go back to regular thigh saver.

    CRITICAL SIZING WARNING: Please be cautious with the size guide, as it seems inaccurate. Based on the guide, I would have needed a Small (I wear a size 2 in pants, with 37"-39" hips). The Small was far too tight (I looked like I was cut in two). I strongly recommend using your known size in the brand's underwear; I exchanged for a Medium (my standard Knix underwear size) and it fits absolutely perfectly.

    Choose the same size as you would for a underware.

    Better than the s-brand

    I won't name the brand I'm comparing this to, but it starts with s and ends with x.

    These are much more comfortable, easy to put on, yet quite effective. It holds in my tummy and smoothes out the saddle bags. I can wear form fitting outfits with confidence. I'll be purchasing more.

    Leakproof thigh saver

    Helps with shaping and security knowing it’s a Knox leakproof item. Highly recommend.
