Whole life
Looking like you tried too hard -- or not hard enough -- is the kiss of death in the world of fashion.
While I find that helpful with relation to how to dress, what I like about it is that it's asking you to exude confidence. It requires confidence to pull something together without trying too hard. It requires confidence to make an effort to look your best, even if you're just running around town. Look like you care, but not like you care too much.
I love the idea of the outside reflecting what's inside and vice versa. It makes us feel whole.
