The light blue ones are from Uniqlo Baby, a collaboration with Paul & Joe, and I bought them at Uniqlo. I think the yellow ones are from Birthday. Both of my children wore these. I don't think they wore them more than 10 times in total, as the seasons didn't quite match up, but they definitely show signs of wear. The light blue ones have some stains. (They might fade if washed properly.) Please purchase these if you understand the condition.
