Would it look bad if I wore the same thing two days in a row (details inside)?

This Friday night is the National Honors Society induction ceremony at my school and then next night is Grad Night at Disney. I'd wear shorts and a t-shirt to school on Friday like I always do, but because they like it when you look nice at the National Honors Society thing and at Grad Night I figured I'd wear my dark black jeans with a solid black t-shirt and an open black button-down over it both nights. Obviously I'd change the t-shirt, I'm not disgusting, but would wearing that same get-up two nights in a row be a bad thing? I don't know how many of the same people will be at both events, and it's not like I'm getting inducted to the National Honors Society, I just have to be there because I'm a senior.
