A friend was depressed because he was infatuated with a certain girl for years and when he finally got to talking to her on the phone, her personality was so lacking he didn't bother asking her out. He said this was a perpetual problem of his, the girls he went out with all tended to be self centered, image absorbed and shallow.
I asked him to describe the girls he typically asked out and you can guess what they looked like and how they dressed. My answer was, "What do you expect?" Next time you see a girl with anorexia and implants sporting a designer purse and wearing clothing that's too tight remember what her personality is going to be like and you'll suddenly no longer be attracted to her.
Then I told him the allegory of the cakes:
You have two cakes, one was purchased from Albertons or which ever grocery store, and it's covered with pink flowers and frosting.
The second is a homemade chocolate cake, where the frosting isn't quite perfect.
Which cake is more attractive to you? Which cake do you want to eat? The homemade cake naturally, because you know it tastes good, and hence it has become more attractive. You see the heavily frosted cake and think, "Woa, that's a lot of frosting, I don't want to be eating that." The cake which someone has put so much effort into looking good becomes unattractive.
What's interesting are those continue to buy the overly frosted cake and then are surprised when it tastes like frosting.
This is not to say that attractive people aren't interesting- it's the heavily FROSTED people that you have to worry about. Tanning, excessive time at the gym, highlights (especially DUDES with highlights) way too well dressed. If a guy could dress REALLY well, I wasn't interested. Men especially need to beware of dating the frosting, once they marry a well frosted lady, guess who's going to be paying for the frosting.
