First Job!

hi!! i’m 17 and have been trying on and off to get a job since i was 15 and finally got an interview for one! i’m super nervous because i REALLY want this job so i can save up for college/car and just have money so i dont have to get it from my mom, ya know? any who, any interview tips?? or what to wear for it?? i would be interviewing for a hostess spot at a fancyish restaurant that only does dinner

UPDATE: got it!! thank you! :)
