Pattern: No pattern! This was an upcycle using a sweatshirt purchased from Walmart
Modification: I stitch ripped off the entire hem band, the neck binding, and front panel from the back and sleeves then placed on this sequin fabric to cut out the shape. I then basted the two panels together and sewed back into the sweatshirt! Tutorial on how I did this.
Fabric: The sequin fabric I got from The Original Sewing & Quite Expo in Chicago, IL. My boss was getting some for her little twins to make them pink and purple sequin sweatshirts and I decided I needed one as well, haha.
