Ballet Costume for Competition

[Moneypenny]

Help please! Dd is shortly due to compete in a ballet competition and we're having problems with the costume she was planning to wear. We are going to be in London Thur/Fri of this week and wondered if anyone knows of anywhere in London where we could buy a fairly simple off the peg costume ... either something with a short tutu or a simple skirt. We'll do the rounds of Bloch, Capezio, Sansha, Dancia etc, but just wondered if there was anywhere else. Alternatively, we could get to somewhere in the midlands on Saturday.
