You know those pop socks (sockettes? whatever other name they go by) - beige coloured things that just barely go over the toes and heels, to wear under summer shoes so that they look like you haven't got socks on. Do they make them in girls' sizes, and if so where do you find them? (Not ones that are like the really thin stuff that tights are made of and they use in shoe shops for trying on, but slightly more substantial fabric, the kind that you could wear around if you took your shoes off indoors). I've got adults ones at Debenhams, but not sure about girls' sizes, or maybe they've just been out of stock wherever I've looked.
