I got these in the stripe for my 11-year-old. He is a size 12, and the only size option for that is 10/12. I was a bit concerned because often mixed sizes (i.e., 10/12) tend towards the smaller size, in this case, size 10. But they fit great! Not too long or short. Nice system for fitting the waste with velcro strips inside. Maybe they'll fit next year too!
