There are old family photos of house parties from the '70s that I like to stare at, of my uncles looking suave posing in a living room like they're at the club about to take over the dance floor. Today, I'm thinking of them and of the exaggerated lapels on their leisure suits, of unbuttoned shiny shirts showing hints of a sun-kissed chest, and of a baby blue suit worn with a relaxed brown polo tucked in.
