DS is 2. When he was younger he had a gorgeous little pair of soft navy cotton trousers as a gift, with elasticated waist and cuffs on the ankles. They were neither bulky like joggers nor skin-tight like leggings. Smart, plain, comfortable, functional. But I haven't seen anything like them in the shops since. Has anyone seen the kind of thing I'm looking for?
I was eyeing the plain Polarn leggings, but I assume they're likely to be pretty tight. It's quite hard to tell with clothes online.
