Almost a perfect Fit We have been struggling to find pants for our tall thin boy. We had resorted to girls leggings, but this year he shot up so high on the growth chart that the leggings were now high waters. I measured him several times, and came to the XL B size, however when we got them they were too long, but fit so well in the waist we decided to keep them as we know he will grow into them. And he finally gets pockets!
