Back in my dancing days (not lap dancing, theatre duh) Internationale was great for costume supplies. When we danced to \"Diamonds Are a Girls Best Friend\" all 12 of us were decked out in cheap bling from Internationale which only cost us a few pounds. Random hair accessories/tights/cheap clothes were used for a variety of costuming needs. I'm not sure if Internationale actually markets itself as a costume shop, but it worked well for us. \n\nAs Eleanor said, if you are under 16 and want to dress like a teenager at a pocket money friendly place, then Internationale is the place. Apart from that, it is most definitely not my thing.
