The shirt fit me really well so I didn't need to take it in. All I really did was cut the arm band of the sleeve and then hem the sleeve.
And then I cut the collar off and changed the neckline into a scoop neck. I used some pretty teal bias tape from my notions stash to finish the neckline.
I also made the back the front and the front the back, and left the buttons from the original collar. I think it gives the top a little interest.
The buttons are all for show as I sewed the top closed when I attached the bias tape.
