Speckled Tweed

Gant Rugger Speckle Tweed Blazer, $595 

Speckle tweed is a fabric that straddles the line between casual and formal. The slubby-looking spots really make a blazer like this less boring while still keeping it versatile enough to rock with just about anything. For a little bit more color, there are speckled tweeds with different-colored dots.
