My book, Japan Ai: A tall girl's adventures in Japan, is coming out this December from Go! Comi ( [link]
It's available for preorder on Amazon already!
Part of the book is about going to Harajuku and cosplaying. I have been cosplaying (costume play) since about 2001. In 2003 I met some girls who would become some of my costuming accomplices, and also very close friends. They are the ones who I took my trips to Japan with.
In the picture, what we are cosplaying, left to right, is Hand Maid May, Utena and Starfire (from Teen Titans).
This is one of the images that was made into postcards to hand out at Anime Expo and Comic-Con this year.
