Actually, for my first day I'm going to wear something totally comfortable. I mean, there really isn't a point when you are going you to be stuck in 5 lectures all day. I mean I may change up through out the day if I feel like it since I have like an hour or two inbetween my second and third class.
Just jeans and a t-shirt. Reason? I'm being home-tutored or doing independent study this year. So no one but my tutor or my one teacher will get to see what I'm wearing so it doesn't really matter to me.
