Thank you Butler for the elegant pairing of grey jacket with light or medium grey trousers. We have a mutual friend in Fred Astaire.
What interests me about studying photos of style exemplars from the 20th century is that they have ideas about how to dress -- the cut of their clothes, the colors they combine -- that we rarely see today. They give us new insights about how to dress, especially when we go beyond approving or disapproving of an outfit, and try to understand why they made certain choices in color and cut.
Just for fun, a photo of Astaire with Elvis and Frank Sinatra.
