    Title perfectly describes the panties

    Perfectly describes the thong

    I find that they are very comfortable and because they go high on my waist if I’m wearing and tight pants over them, it doesn’t show the panty line so it’s perfect where as the shorter thongs do . But I also like the shorter ones

    Terrible fit 3 times over for Knix thongs

    I want to love this item but the design of it is just all wrong. I own 3 pairs right now. All ordered on different occasions. The first Medium was cut way too big even though the waist is a perfect fit and comfortable. The thong is 2 inches too long and the gusset is not wide enough and causes this pair to shift sideways and forward. The second pair I ordered in Small hoping it was the solution the previous problem. No, it was worse, the fit was too small and unbearable. Their third time I ordered this I ordered it in Medium again. The fit was still a whole lot of fuss. The waist is a little smaller, but still fits comfortably, the thong is 1 inch too long and shifts forward all the time. With the gusset still not being wide enough again, it just rides forward and shifts sideways making the wear completely uncomfortable. I've bought other thong styles from Knix and still run into the same 2 problems, waist fit is ok, gusset too narrow and the thong way too long and the garment never sits right, which makes these ineffective period underwear for me.

    Fits a little big

    Love that it’s seamless and the high rise fit. It stretches out very quickly though so I should have sized down.

    Love these

    This fits true to size. High rise is a perfect cut. Nice smooth feel that doubles as shape wear. Perfect for everyday wear. They wash well, in a mesh bag in cold water cycle, and I never put them in the dryer, air dry only. When you first wear them they may fit snug but stretch over time. For instance I wear a size 28-29” pant, or 8-10 pant and purchased a medium in these. Wish they came in more colours.

    I think I need a medium.

    The large is too large, I actually need to try a medium.

    Love these!!!

    I’m already a fan of the light leakproof thongs for everyday wear. I decided to try these for the high rise compression and they did not disappoint. Will be ordering more!

    unflattering

    I really wanted to love these, unfortunately, they are incredibly unflattering, I feel like they draw attention to my love handles and the fact that they do not provide full coverage in the front.
