The cycle of suit jacket styles - 1950s, the late 1980s, the early 1990s and today

The photo above is taken from voxsartoria's fabulous website about style. It is from 1955 and you can see musician Glenn Gould in a navy blue Double Breasted blazer/sports jacket and a pair of very loose fitting trousers. At first I thought this was from a Giorgio Armani advertisement from the late 1980s or early 1990s
