What do you do to make you look hot?

Does it really mean you have to show some flesh when you want to be hot, like highlighting your cleavage, and wearing very short skirts? I need the opinions of both boys and girls, and tell me what's your definition of "hot" because for me, one can be hot without exposing everything. One can be hot by puckering up a pout, decorating one's eyes, having a good hairstyle, or simply flashing a radiant smile...
