Here's a Garrus and Tali ME3 reversible hoodie that took me a fair few weeks to make.
I know that Bioware are making some, but I got a tad bored waiting, and as I sew/design myself I figured out how to go about it.
The design is based on Bioware's characters of course, but I created the version you see there, simplified for cloth. The hoodie pattern is my own design, based on my own measurements and clothes design know how.
Hope you like it!
Also - pyjamas!
