Best place for boys pants? 7 year old. Relatively thin waist, but bigger thighs. Rough on clothes and would love for them to last/he grows like a weed and I don’t want to spend much when it probably won’t fit next winter. Currently has some Costco and some cat and jack. The waists if the 6 fit, but they are way too short. But bigger sizes would fall off. anyone have a lead?
