it is a tutu
The song is 'You Belong With Me', and the lyrics say 'She wears short skirts, I wear T-shirts'.
White T-shirt Black Trousers,Skirt or Short
Something informal but not just jeans and a t-shirt make it something like a long skirt and glittery top. remember you're going to see a ballet not meeting the queen!!!!
I do ballet, so you have to wear tights, a leotard and a skirt, plus ballet slippers.... it may be different though in other ballet schoolsThe usual boilerplate wardrobe is:For girls--A uni-tard, tights and slippers (or perhaps Pointe shoes).For boys: A T-shirt, dance belt, tights and soft slippers.
The letter T is silent.
