What U.S. city has the most vain residents?

Mirror, mirror, on the wall -- which is the most vain city of them all?

Model-centric Miami, according to the LivingSocial website. Next on the vain list: Chicago, followed by Atlanta, Philadelphia and Phoenix.

Huh? What happened to L.A., where picture-perfect actors wait tables and park cars and aspire to be the next Brad Pitt or Angelina Jolie? It ranked sixth. Or New York, where Botoxed socialites and fashionistas strut Madison and Fifth Avenues? Ninth.

LivingSocial surveyed 4,000 people online in 20 U.S. cities.
