I received 6 packs of black, blue and gray for my daughter size 5-7. She is 5 years old and about 41 pounds and they fit great. I don't know if they last more than a year. They are very thin but since I have darker colors I don't see them showing through. Perfect for lounging at home or worn under skirts or dresses. I would recommend.
