What is the Costume Reference Library?
Costumes in the 501st are grouped by detachments, each representing a collection of members passionate about that particular set of costumes. These members have worked to assemble these guides to aid you in creating your own costumes and joining the 501st!
Each reference guide contains pictures of the costume, a detailed description of the parts, and requirements for 501st membership.
