Halston meets Andy Warhol–look. Neither of them would care about the traditional white dinner jacket rule. Halston favoured a lighter jacket worn over a dark roll neck and Warhol wore denim with blazer and a tie. This look is very casual and a little “riviera style”, but the festive attire doesn’t have to jingle—it needs to mingle. Just add smallest Cartier Tank you can find and you're good to go.
