Dd has a ballet exam on Tuesday and her dance teacher sent out a letter yesterday with a list of things she needs, bobby pins, kirby grips, bun net etc which I've managed to get hold of but she has to have pink ballet socks (which she has) with shearing/shirring elastic sewn through the top?? Anyone got a clue what I'm supposed to do? I'm useless at this kind of thing. Any help is massively appreciated.
