1
Put on the light yellow collared shirt and button it up to the top.

Tuck the yellow shirt tightly into the trousers so the waistline is clean and visible.
4
Thread the white belt through the belt loops and fasten the gold buckle directly in the center.
5
Put on the white socks and black canvas sneakers.
6
Style your hair using temporary green hair spray, or put on a wig cap and secure the short green wig.
