I bought these, but my child didn't crawl for very long, so I barely had a chance to use them. Worn 1-2 times. Made of soft T-shirt material, I think they'd be cool and comfortable to wear in the summer. They're not tight pants, but rather short pants that look like a fluttering skirt. The polka dot print isn't peeling; it's part of the original design. The color looks a bit white in the photos, but it's actually a bit more pink. Please understand this before purchasing. I bought these at Birthday, a children's clothing store. Feel free to ask any questions☆ Instant purchase is okay!
