You can learn a lot about people who consider themselves single-issue voters when you find out what they consider to be the single-most important social issue facing the US today. Similarly, a person's favorite band – or their favorite food – can be revealing far beyond music or gastronomic taste. In reality, there are just some things people can like that immediately reveal their taste and preference subtleties at depths beyond the surface.
Fashion choices are no different. The choice of a hat, or the fit of a shirt, or the amount of jewelry someone wears might just reveal everything you need to know about a person.
