I bought a couple of pairs of these in toddler sizes because they were a really good price - under $8 a pair. but, when you put them on the baby, the cotton stretches, pulling the print apart. the ones I used are pirate print, and they looked old and faded after the very first time he wore them, and they're still too big. I don't know if that's a function of organic cotton, or just cheap screen printing, but I won't be buying any more!
Thanks for the heads up. I saw these last Thurs and almost bought my 4 yr old a pair but it was $11 that was not on our list so we didn't.
I hope you have taken these back and got your money back. Costco does have a great return policy and customer service. We've had to return some canned mandarin oranges a while back for having some sort of grease on the tops. Anyway, they were apologetic and returned them as well as giving us an extra gift card.
