I have this black shirt, that was fine but honestly it was a little tight and I didn't love the way it fit. So, I cut it from the bottom to the neckline, leaving the neck hem in place. Then I added 3 inch strips of fabric to the front and back so they would peek through. I added a little tie around the neck to add an extra flair.
It took me about 20 minutes from start to finish. I love that I totally revamped my shirt to look so different in such a short amount of time. Easy peasy.
