What to wear: Charlie (may she rest in peace) is pretty casual, but she's a self-professed nerd, too. Think hoodies, shirts with cats on them, and anything that has a techie sort of reference. Also, finding a way to nab that red hair wouldn't hurt.
How to act: Charlie's brazen, sassy, and always ready to go all in. She's stronger, smarter, and more resourceful than she looks.
