Over the weekend, Onna! posted its Cosplay information.
There's both the Main Stage Competition event, then an event called "Harajuku Fashion Show". It's not so much costumes from anime/manga series, as it is letting people do their take on Japanese youth styles (such as "gothic Lolita", double-dutch, J-Pop/J-Rock, etc.).
Just to warn you, I *do* work as staff there, so forgive me for doing a little advertising. But wanted to let everyone know that yes, Cosplay info is up!!!
