Mychael, you can find a similar shirt in some of the pattern catalogs, like Simplicity or McCalls, but they need a little modification. To me the sleeves and lacing look too costumey so I found a regular pullover shirt pattern widened the sleeves just a bit and skipped the cuffs. I made it out of muslin I got for $1 a yard. The pattern I used is Kwik-Sew number 3250, View A. It's close enough to be easily altered. Kwik-Sew prints patterns on heavy stock so I trace them. That way I still have the original pattern undamaged for later use.
