As wedding planner Marcy Blum explained to Vogue magazine, I always call Black Tie Optional the passive-aggressive dress code
Each event has its own tone: Cocktail parties : Sleek midi or mini dresses, often bodycon or slip styles Formal parties : Long gowns, dramatic fabrics like velvet or silk Festive events : Bright colors, sequins, fringe, or sparkle Club nights : Shorter hemlines, cut-outs, bold prints, or sheer panels Designers adjust the level of formality by changing fabric, embellishment, and silhouette
For a more traditional vibe, swap the sneakers for a pair of black leather oxfords or pointed flats and tuck the tunic in slightly for more structure
It also fits perfectly into most contemporary office dress codes
