i might have made this look more complicated than necessary, because i'm the kind of person who likes every little thing spelled out. only four of these steps (6, 8, 12, 13) actually involve sewing. yellow is right side of shirt, turquoise is wrong side. let me know if you have questions or i wrote something unclear or wrong here.
by the way, the cool clever part of these pants -- using the sleeve hole to make that weird-shaped part where the legs join -- is not my own idea. i got it from supatropic's shorts in the memories: http://www.livejournal.com/community/refashion/103246.html
