This doesn't have to be a pack of 6 - it arrived as two separate packages of 3 (one of each color). The crotch area is small, as other reviewers have noted. I'm mostly annoyed that they made me buy 6 of these when I would have just bought 3 to see if they fit. I think the seller is trying to get rid of them by bundling the packages together. They fit my fairly skinny 3 year old and I'm having trouble finding other 3T underwear for her at the moment so we'll keep them.
