I used Simplicity Pattern 2832
Looking at the pattern, my final product doesn't seem to match. But if you look closely, you can tell it was made using this pattern. I knew I wanted a puffy sleeve. I also knew I was going to want a half skirt as I was going to pair it with shorts.
I'm also currently working on a new cosplay that this idea applies to, but I don't want to give it away. Therefore, once I'm finished and debut the cosplay, I shall add another post.
Until next time!
