Perfect Looks? Ain't Ever Going To Get There?

You how you see some girls and they're just perfect. Have perfect teeth, hair, skin, body and all the rest of it.
And then you see a girl who has a big-ish nose, or crooked teeth, or pimples and she's still pretty?
Well, does perfection add up to beauty?
Is your best friend/girlfriend//boyfriend/you have a pretty big flaw in terms of looks, but is still really pretty/good-looking?
