I had this shirt and I liked the design on the front, but it was elastic at the bottom causing it to bubble which I didn't like. I decided to change it and this is how it turned out :)
I don't have a before picture, but there was elastic at the bottom so I just cut that off.
Just cut a straight line down the middle. This shirt was somewhat of a v neck so it left a point. I just trimmed up the top to make it curve more.
This shirt is 60% cotton and 40% polyester so it didn't fray.
