I'm a little torn on which pants to wear with a navy blazer in semi -formal situations where a suit would be overkill. For more casual situations, I simply where dark denim. What about the in between areas? A few thoughts: Navy - obviously out Grey - I am leaning towards this, but many feel it gives off a security guard like feel Khaki - feels way too preppy for me Brown - maybe? Any suggestions for colors or textures that work best here?
