I adore vintage, antique everything really, but making vintage fashion work can be a little tricky. You can go overboard and look like you've stepped out of the bad 1970's with the bell bottoms and green crochet scarf. The 50's...not so bad, but this era did give birth to the embroidered and tropical shirts! Mixing some vintage with current fashion is the key, but then I think you have to find that balance also.
While doing my usual research I Stumbled upon this great website. http://www.fineanddandyshop.com/
It's a New York based company that specializes in men's accessories...but just not any accessories - Classically inspired accessories like what grandpa or great grandpa use to wear. Mix a few of these pieces in your wardrobe for that dapper look.
Great shots below are from Scott Schuman "The Sartorialist". This is what I mean by "The Dapper Gentleman", but with a current twist.
