I left my old job with a few of their shirts (I don't know if I was supposed to hand them back in, no one told me to and really who would want used shirts). So I've used some as linings for things, but for this I used the top of one of the shirts in a top. I liked the idea of being able to see that it used to be another shirt.
I've said shirt too much.
I cut the top of the work shirt just under the arms, and attached some pink jersey. The jersey wasn't long enough on its own, but it was twice as wide as I needed. So I cut off the excess and added it as a frill/peplum. It now looks like a super short pink tennis dress.
