For the hoodie I bought a giant men's hoodie and chopped it and reassembled it to fit me and also added the pink lining to the hood. To make the design, I sketched out the pattern and traced it onto contact paper. I then gave it a layer of white paint to help the colours appear brighter, and then added the pink and blue. I have some in progress shots on my phone that I'll upload later that show some of how I made it.
The wig is just a plain black wig that I added coloured extensions to. The ponytail was really difficult to create with a wig, I discovered, but I used a LEGO rubberband to keep it together because oops, who needs to own real hair bands? It will need a bit of work for future use, especially given that these photos are after I was wearing it for several hours, so it just all went *poof* and became a hot mess.
I am planning to make the pants and shoes at a later date, because oops, didn't have time and we were slightly snowed in. Definitely planning on taking this to some LEGO and comic conventions!
