What should i dress my brother up like tomorrow and the next day?

So my brother is letting me give him a "girly week". I get to do whatever i want with him(including clothes and stuff). He's gone shopping with me and gotten a mani-pedi with me today, we had a spa day at home(facials, pedicures, etc) yesterday, and we went to the beach in bikinis on Monday. What should we do tomorrow and the next day. Please include outfits!
