These underwear were exactly what I was looking for. The material is thin and very stretchy, making it comfortable and totally invisible under clothing. I have work them to workout in, under jeans, as well as under tights with a form fitting skirt. The stretchy material and lack of seams on the edges makes it sit so nicely on my hips and bum, not leaving any lines at all. After trying these out I immediately ordered 3 more pairs online-- these are definitely a new go-to underwear for me!
