Opening Ceremony has opened its online store. Opening Ceremony's physical locations in New York and Los Angeles carry fashions from a different country each year. There's a description here of the stores on New York Magazine. The L.A. location has a big Hello Kitty house according to LAist.
At the new OpeningCeremony.us website Hello Kitty floats across the screen in a blimp. OpeningCeremony.us carries both men's and women's fashion. Some of the designers currently carried include Alexander Wang, Tsumori Chisato and G.V.G.V. There's a staff picks selection here, which is worth a look.
