Halloween Cosplay Suggestions

Did a poll for costumes last year for Bird (Sakura from Street Fighter won), so I'm bringing it back for Nid and Bird respectively-- you can comment down below some outfit themes based on Halloween theme or cosplaying of existing characters for either character, and I'll pick the most fitting ones and make a small poll for both Nid and Bird!

I'm only going to take five options for each of them, I'm kinda blanking so I could use some help to decide on some ideas-- thank you :)
