someone give me advice

Kayla
hi all! 
so i've been talking to this really good looking guy on snapchat recently and we have gotten to know each other quite well and have played t or d a couple times not gonna lie. and i've decided to meet him in person by coming to his bball game tomorrow with one of my friends. i'm actually nervous and i know i shouldn't be and i should be myself. but what if i'm awkward towards him? he's really nice and i don't want to fuck it up. can someone give me advice about what i should do tomorrow? like what do i wear? how do i talk etc. thanks :)
