My babies wear underwear in one size 5 and 7 and while superheroes, dinosaurs and sharks LOVE to wear underwear "just like daddy". They are very stretchy with spandex in the material and are perfect for both boys (45-50lbs). All 5 packs are in "dad colors" and they walk around in their underwear. The spandex in the material prevents fading and I wash with like colors.
