This holiday goods store has bounced around Shanghai since it opened in 2006, but it's still Ruby running the shop. Packed to the rafters with a well-organized arsenal of holiday stuff, including kid and adult costumes from the California Costume Company, ornaments, balloons, props, accessories, fake blood, pinatas, etc. They have a pretty cool costume leasing arrangement where you can rent out an outfit for 24 hours instead of buying it. They sometimes extend opening hours in the run-up to holidays. They also provide catering for parties and events.
