First off, it was a little tricky because the shirt had raglan style sleeve, which just means that the sleeve seem goes from under the arm to the neckline, rather than to the shoulder. I couldn’t didn’t want to take off the binding on the neckline to re-do the entire shirt. This is the EASY way to take in a shirt, not exactly the “right way”, but who needs to do things the right way? c’mon!
This is 2 steps…. ONLY 2! Step 1. Turn it inside out and pin along the side, going up the sleeve as well. Do this while you’re wearing it (put it on inside out), or you can lay out an existing shirt over it and match the shape. I put it on and eyeballed it.
