    These are amazing! The material is so soft that I literally forgot I was wearing them. I tried both the high-waisted bikini and the thong and loved them both. They’re incredibly comfortable, flattering, and feel really high quality. I’ll definitely be buying more!

    The bigger gusset has opened my eyes to how uncomfortable we have been living and what women truly deserve in a pair of underwear.

    THESE ARE GOOD. They’re so soft and feel like I’m not wearing anything! They didn’t ride up throughout the day I love the feel of the material. It’s soft enough to be comfortable but I still feel like I’m not going to slip out of them.

    I loved how soft and stretchy they are! It really felt like I didn’t have any underwear on. The fact that the gusset part is stitched down so it doesn’t give me a cameltoe or rub my crotch is AMAZING. I love that there is no tag, so I don’t have to deal with it hanging out or rubbing on my back.

    I’m overall blown away with the overall quality and the fact that I forgot about my underwear while wearing them. Super comfortable and cannot wait to see what else is in store!
