It's been a long time since I've refashioned anything. I recently came across this lovely blue polka dot shirt at a thrift store, and just loved the fabric and the pattern. It was an easy fix and more of a alteration than a refashion, but whatever.
Basically I just took in the sides and the arms. If I wanted to do a proper job, I really should have taken out the sleeves, altered them and then put them back in. But I was lazy. No worries, it still turned out perfect and very comfy.
It can be worn with jeans or with an awesome skirt.

And it is 100 percent jump proof.
