Start by cutting around the neck of the shirt.
Take a white pencil and trace what you want your neckline to look like. We are cutting a deep V in ours.
Next, cut along the white line you drew.
Step one is done! Now off to step two. We are now going to cut slits in the shirt. Be intentional about where you choose to cut the holes. You don't want to add too many.
Go in with a razor blade and gently take it across the fabric to create frays. Do this on the cut outs and wherever else you want.
