    Great product but size up

    My daughter is a big fan and especially appreciates how thin these are compared to other brands. They do run small. She usually wears SM but I ordered M based on other reviews.

    For dance

    My teen is a serious dancer, and was having issues with leaking. We were so happy to find this underwear in a nude color, so that it can blend seamlessly under her leotards. True to the title, it also does not leak, even through heavy dancing!

    Cute trio- vivid colours

    I purchased the shorts and the trio set. I'm always happy with the products I receive. The sizing chart is accurate and the quality really good. The only downside is that certain products are expensive and I prefer shopping when items are on sale.
