Step 1: Cutting pieces 1 & 2
There are 4 pieces to this shirt. Three in the front and one in the back.
Starting on the front top section fold over the shirt so you just see piece 1.
Cut the piece out 1/2" larger than the original. This shirt was tight in the arms so I extended the length of the armpit to the shoulder.
Flip piece 1 over and cut a copy. This is piece 2.
Step 2: Cutting Piece 3
Cut 1/2" wider around the bottom piece. This is piece 3. I lengthened it by a few inches because my sister is long waisted. If you are going to hem the shirt account for the added hem. I didn't hem the bottom because I didn't need to. The spandex will roll up a little around the bottom and keep from fraying
Step 3: Cutting Piece 4
Cut 1/2" wide around the shirt. Again I added a few inches to the length.
