I bought these for my preschooler for her dance class, but have also used them under dresses. Baby dresses seems to always come with little bloomers to cover diapers, but when they hit toddler-hood, the dresses don't have anything to cover diapers/undies. Now that she is potty-trained, I don't want her flashing her underwear when she's in a skirt or dress, so these are perfect. They are nice and soft spandex-y material, and very durable. They are thick and I'm not worried about them ripping or wearing out. Great, great, great product!
