Dengeki Layers is a new magazine devoted to cosplay--not just showing off lots of photos of cosplayers doing what they do best, but including patterns to allow you to make your own terrific costumes! Includes one full-sized pattern (S,M,L) and pages with patterns for other costumes, that must be photocopied and enlarged to be usable. The full-sized pattern in this issue is the one-piece dress (as seen on the front cover) from "Space Stellvia." All text is in Japanese.
