Men (at least the highly fashionable ones) wore many accessories in the 1920s. Notice the different types of hats (here we see fedoras, straw boaters, and Newsboy hats). Canes were popular accessories as well as small rings, tie pins, and collar pins.
I love both these styles of coats; firstly to the left we have a fur collar Parker - you cant really go wrong with this style jacket, perfect for stylish guys who wants that quirky edge. On the right - a fur lined and collar denim jacket, personally I love a guy in a denim jacket showing off the authentic feel, vintage is everything.
