My son loves these underwear and thankfully he'll soon grow out of them because they are such poor quality, I don't know how many more washes they'll withstand. The elastic waist is coming apart on almost every pair, and after so many washes, the cotton is still pretty stiff. I also agree with most reviewers here that I had to buy a size up for my son, and they are still a little tight on him... And he's a skinny boy!  I have Petit Bateau underwear I've owned since the late 90s that have yet to show any wear. I guess you get what you pay for.  Overall, if it weren't for the Thomas print, there's no way I would recommend these.
