An actual theatrical supplies store for Peking opera troupes. They make the outfits themselves. Full-on outfits are available here, from those fancy headdresses, starting at 800rmb, big old thunder god beards for 150rmb, to the tunics and dresses for 180rmb and up. If you want to go to a party dressed as King Xiang Yu, this is your spot, though ask yourself if you're the right person to co-opt a treasured cultural artform for a stag-do. The store-owner can be a bit stand-offish, and doesn't appreciate people traipsing in and pawing the goods. Do your research beforehand, and behave yourself while you're in there. The hours are a little irregular.
