Wig- Arda's Ferrari in Platinum Blonde, no styling.
Hat- I used the Finn hat pattern on the Instructables website and made some modifications to it. It turned out really well and it's totally cute, but it's still too Finn-esque with the flat top, so I'm going to remake it.
Shirt- Made with spandex using an old t-shirt as a pattern. It was simple enough other than the sleeves not fitting quite right into the armscyes because my pattern was derpy. Oh well.
Skirt- I drafted my own pattern using SecretLifeofaBioNerd's YouTube tutorial.
Socks- Ugh, these were a nightmare. Most of it was because my good sewing machine crapped out while I was working on them, so I had to use my crappy one, and after 3 attempts and 1 anxiety attack later, I resorted to hacking the legs off a pair of tights for Halloween. I will get a new pair soon.
Shoes- The shoes I got 3 or 4 years ago from Walmart. Originally, they had off-white stitching that I painted over with black acrylic paint. Easy peasy.
Best Costume at a Halloween party! Woo! :P
