In the beginning it will ask you if you're a boy or a girl. (Don't worry I won't know so whatever you say remains a secret.) Once you do, depends if you're a boy or girl, you get 4 pictures. Between your friends click on what you like best. If you have a friend group of boys and girls, split into 2 groups, only boys and only girls and answer it 2 times. Once as a girl and once as a boy. The music will play forever so when you're done filling it out, you can press the stop button. The point of this is to know your sense of style in your friend group.
A big thanks to CS First.
