What's fun about cosplay is you're always learning and improving. It's so cool to see how much you've improved. You always learn new techniques and skills. I put on a costume I made in 2018 and was excited because I knew if I remade it there would be so many new techniques. Seeing yourself grow is always really fun.

People are afraid to start cosplaying because they won't be the best... But that's a silly thing to strive for. Just be the best you can be and make each costume a little bit better than the last.
