If it's a pink song, it's better to wear light clothes, and it's better to have some characteristics.
For example, a girl can wear a skirt, a furry thing around her neck and a pair of boots without orders. Boys wear shirts without buttons on the chest, casual pants and a pair of nice sneakers. Girls are cute and boys are handsome. )
If it is a sad song, you can choose white and all white.
If it's a rock song, it's better to choose sapphire, black and crimson. It's best to wear leather, and boys wear a skull-like necklace on their chests. Girls wear big earrings, preferably round ones with small broken diamonds.
I don't know if it will help you, because this is my own idea, so there is no picture, sorry!
