These are really cute and comfortable.they are made with my signature gusset design so they don't ride up uncomfortably in the crotch. I added a roll down waist on these so these are an elastic-free design. Made from a second hand material that I got I'm not sure if the fiber content but doing a burn test it appeared to be a blend of both cotton and synthetic knit. Both of them are very soft and stretchy these fit a small or size 26 to 28 in Waist best
