Where do you get jeans for your tall & skinny boys? One of mine is 3.5, the height of a 4T-5 but waist more like 2T-3T. Several people have recommended Old Navy in the past but I don't see the drawstring jeans anymore. Tried Children's Place adjustable but even those were at least two inches too big in the waist. Last year I just didn't buy jeans at all since they have better luck with sweats...but this year they (twins) are going to preschool so I'd like some jeans/cargos/non-sweat pants.
