Bruno Mars is many things. A deft crooner. An adept songwriter. A snappy dresser. Possessor of a dazzling, charming personality. All those things are indicative of the singer. His personal style harks back to the Rat Pack era, and Mars is a man of many, many hats. He is rarely seen without a topper, usually a fedora. In honor of his 28th birthday today (Oct. 8), we've assembled a scrapbook of the crooner and his caps.

We could look at him all day. Really.

Oh, look! A knit skully for Bruno Mars. He owns this type of hat, too! We love seeing him go casual with the skully and a flannel. He's superb even when dressed down.
