    Sleek briefs

    These briefs are great under pants or a dress to give on smooth lines. Just wish they came in super leakproof as well.

    So in love.

    This were the best shape wear, I have ever worn. They kept their shape the entire day. Most will stretch out, after a full day. I was able to breath and move all day, yet everything stayed put.

    Perfect for my wedding

    Unfortunately I’m due to get my period on my wedding day and was so worried until I got these! I am usually a medium in underwear so ordered both a medium and a large due to conflicting reviews about size. Turns out the medium is prefect for me. Prefer them to my HoneyLove ones actually in terms of comfort.

    So happy I don’t need to worry about period or leaking through a tampon on my big day now. Thanks Knix!

    Uncomfortable and sizing is off

    I was super disappointed by these! I really like everything else from Knix and am a true size medium. I got a large in these and they are so difficult to put on, very uncomfortable and stiff, yes I know they are shaping but I have used other brands of shapewear and these are much more uncomfortable. Based on the underwear I would have expected these to comfortable. Aside from the uncomfortable ness of these, they cut off in a really bad spot. I feel like I would actually need an XL in these but not willing to try.

    Smaller than usual and pad in incorrect position

    These briefs are good overall but would be better if the sizing was consistent and if the pad started higher in the front.

    If I sized up probably this would work better.
