The question is: What should be done? One proposed solution that has been kicking around for some time now is the Fashion Police. The way I envision this working is, you'd have people in very tasteful uniforms patrolling public places, monitoring the clothing of civilians and taking whatever corrective actions were necessary. Usually this would consist of a simple polite oral warning, such as:
"I am sorry, sir, but the 'muscle' shirt is designed to be worn by people who have actual discernible muscles, as opposed to rolls of fat large enough to break the falls of world-class pole vaulters."
"Madame, we do not wear fake-leopard-skin hot pants and very high heels unless we are a 15-year-old girl who cannot even pronounce the word 'cellulite.' "
