Brighton Ballet School

First ballet lesson soon?

hey, me and my friend are going to start at this dance centre in town. i'm going to do ballet and she's going to do street dance. i'm sixteen, and i've not really had any previous experience of ballet before. i've emailed the teacher, and she's said that i can start. i'm going to do a beginners class. i was wondering though, what should i wear to my first lesson? i havent got a leotard or anything. i've got tights (black though), and i've got a white camisole thats leotard material.. i'm not sure what to wear? also, im not sure what to take with me.
any tips? what shall i expect for the first lesson?
i'm really excited ;D
thanks so much <3
