We got these for my daughter to wear under her dresses as that's her current preferred play clothes and I was tired of everyone getting to see her underwear. These are technically a little large on her, but the size is 4-7, and she's a 4 so it makes sense. And given what I've seen so far, these are going to last quite awhile!
They feel like a really thick tights material, and are not see-through unless stretched. They feel super-comfy, and I kind of wish they had them for women. They have washed really well (always air-dry!), and stood up well considering my child is the one who never stops moving and loves being outside. The ingrained dirt-stains on the bum I've just learned to accept, as we were blessed with red clay in our area and it does that to everything. This is exactly what I was looking for at a price I can get behind and I would absolutely recommend them to anyone else looking for a way to keep their kids in dresses from flashing the world!
