I decided to take this opportunity to add an upcycled costume to my growing wardrobe of running costumes.
I first started with a black 100% polyester shirt (same material and feel as other running shirts) that I found for just $4 at a thrift store.
Step 1: I took off the sleeves at the seam.
Step 2: I chopped off the bottom of the shirt at the waist to make the final vest shorter.
Step 3: I cut a vertical line down the front middle of the shirt to transform it into a vest.
Step 4: I hemmed the arm holes and the bottom hem of the vest.
Step 5: I used the leftover fabric from the sleeves and the shirt bottom to make pockets based on Internet pictures that I found of Han Solo's vest from "Star Wars Episode IV: A New Hope." [If you're not already aware, Han Solo has different vests for ANH and RTJ.] No, I did not use a template; I just eyeballed it and cut.
