After some thinking, I realized the bottom of the top would work as a skirt. So I cut the shirt right below the armholes. I wanted to leave excess in order to work some sort of waistband.
Next I serged the edge of the top to avoid fraying.
Then I decided on something smart.... I left the existing elastic in and sewing the top part of the skirt to the underneath of the skirt. Essentially making a casing..
Basically I had to stretch while I sewed... but I got a picture!
Done! Now to have some fun styling it!
