Just a note up in case anyone is looking for Julienne & Porselli. Its now closed down. However if you do end up around there, its a short walk to Drury Lane (down Long Acre) where you can find Blochworld (nice looking shop, bit useless in the clothes department) or the Very Pink but Extremely Helpful Dancia (seriously, don't let the colour put you off) where I have ordered some Grishko vegan ballet slippers. The place with the biggest range of leotards I have found so far is Sansha which is tiny and crammed.
All three of these shops are within a stone's throw of each other and seem to be open later on Thursdays.
