    Lots of fabric, lots of wedgies

    This fabric feels incredibly thin to the point of not providing enough support. I absolutely love ThirdLove’s older all-cotton briefs and keep trying to replicate that feeling of full coverage. Unfortunately, these briefs present this weird dichotomy of having too much fabric (the most high-waisted I’ve ever experienced) that is too thin to provide the sense of coverage I’m seeking. Every lump is visible (and to be fair, these aren’t marketed as smoothing), and I just felt incredibly grandma-ish. I only wish I’d tried one pair before purchasing a bundle to save $$$. Now I just have briefs I push aside in the drawer in search of my oldies-but-goodies all-cotton briefs.

    I loved the bras so

    I loved the bras so much in this fabric, i decided to try the underwear. They are by far my favorite underwear! They are so breathable and soft. They feel cool and are not tight at all. I am usually worried about it being tight around my leg/butt area and these are perfect! I will be ordering more!

    So comfortable

    These are perfect for everyday wear! They are very lightweight and smooth, and stay put. Especially good for warm days but I'd wear them any time.

    This fabric is amazing, and

    This fabric is amazing, and keeps me comfortable all day long. I also love the shape and the fact that the top does not roll down.
