I am fifty one and have been wearing tasseled loafers since I was twenty. I have several pairs, the oldest being a very sleek pair from Tricker's in a snuff suede. I special ordered them in 1988 and they still have their original soles and heals. The price was eighty five dollars.
I have only one pair very similar to the ones you posted and I am currently 42, I have worn tassles in the past in my 20's and 30's but I would say that they don;t quite look right on a man who is too young, it makes him appear as if he's trying to look older then he really is.
