If the dress code is "lounge suit," women should wear an elegant dress or a tailored black two-piece suit paired with a dressy blouse. Lounge suits are mostly worn for both daytime and evening business affairs or various social events such as lunches, dinners, weddings, receptions and christenings.
"Lounge suit" dress code is a little more formal compared to "cocktail attire" dress code. A cocktail dress with sleeves or a matching jacket is a good choice for a lounge suit. Ladies can also wear an elegant 1950s-inspired outfit of a duster coat worn over a pair of pants or a skirt.
