Casual- Casual does not mean sweats and a t-shirt. A pair of nice jeans, cords or khakis and your favorite shirt or sweater will do the trick.
Chic-When an invitation says chic, it generally means the host/hostess is stylish, get creative and make use of trends.
Formal- Formal wear usually means the same as black tie, but in trendier cities it could mean a black shirt, no tie with a tux. Men can wear grey, black or navy (unless otherwise specified as black or white tie). Women can wear cocktail, long dresses or dressy separates.
Cocktail Attire- Short, above the knee, elegant dresses for her and dark suits for him.
Black Tie- Formal attire; Men wear tuxedos, women wear long gowns.
White Tie- The most formal evening dress code in Western fashion. Men wear a dress coat, white bow tie, waistcoat and starched shirt. Women wear a ball gown.
Grown and Sexy- Should be removed from the dress code list...this doesn't mean anything and sounds silly.
