There was a hot trend a couple of years ago that I could not stand - men's two-toned shirts where the collar and the cuffs were different colors than the rest of the shirt.
You can still see these shirts around, but not nearly as rampant as they were, thank heavens. I really can't figure out why I don' like them, as any dress shirt is quite nice in comparison to, let's say, a t-shirt, but I think I'd almost prefer a t-shirt.
Random, I know. I rediscovered my displeasure with these in Las Vegas this past week when I maybe got a little too passionate about my dislike.
