Got an invite years ago that just said cocktail attire. No other detail. I turned up in a business suit, tie and all and spent half the evening feeling overdressed next to guys in open collar shirts and blazers. Nobody tells you what this dress code means. You just have to work it out, usually at the event itself, like I did. Men’s cocktail attire shows up everywhere, weddings, work “Men’s Cocktail Attire: The Photos Told a Different Story”
