I started with a hoodie sweatshirt. The plan is to use the extra material from the hood to make the collar. I will remove the zipper and replace it with a button. I thought about how to sew buttons on the sleeve and move the pockets so that they are slots and more professional, but I like the way this looks. I use several coats and hoodies, just pretend all the hoodies are the same one and all the coats are the same. i did it because i didnt want to cut up the nice hoodie until i was sure it would work.
Step 1: Background
I have been looking for templates and sewing patterns to make a sport coat or blazer for a few months with no success. I was curious how complicated it really is to make the coat and because there are no resources for sports coats I'll post my results here. I chose to make the collar a different material than the coat so it shows up better in pictures.
