If there's no inner peace, people can't give it to you. The husband can't give it to you. Your children can't give it to you. You have to give it to you.
When you have a gown, there's much more to be concerned about. Where is this crease falling? Are you making a weird shape with the dress? Are you doing the designer justice? With a bathing suit, it's more about you and the mood you convey.
