Calling all girls with style?

My brother lost a bet o me and my friend Jamie. He insisted that "girls can't play sports" and lost to her in basketball. She had bet him that I she won he would have to dress completely as a girly girl for as long as the people who answer this question sayy. For howerver long you girls say he has to live completely as a girly girl and can't wear anything a girly girl wouldn't want to wear. What should we make him do to be girly and what should h wear? Ps we figure at least a week
