The always dapper Cary Grant.
This particular piece of sartorial wisdom comes to us via Put This On. Here it is:
“Someone once gave me a very fine description of Cary Grant’s attire at a time when the motion-picture star was considered the best dressed man in this country: ‘I’ve been with Cary Grant a dozen times lately, and when I leave him I have the recollection that he was beautifully dressed. But, for the life of me, I can never remember a single thing he was wearing — his hat, shirt, tie, suit, or anything else.’ And that’s what all of us should try to achieve — the impression of being well dressed without wearing any one article that blatantly sticks in a person’s memory.”— Bert Bacharach in Right Dress (via Dandyism.net)
