I (22M) have wanna ask out my coworker that I have a bit of a crush on (19F)

Yo! So, all my coworkers are all between 18 & 24, with a few exceptions. One in particular, I've developed a bit of a crush on her. I'd say we're pretty cool but we've never hung out or anything outside of work. There's a county fair coming up and I wanna ask her if she'd like to go with me. I'm a bit of a nervous individual but I've recently been working on coming out of that shell a bit. I wanna do it in person rather than via text. Just wanting advice on the best approach fr lol
