What is appropriate cocktail style? This has to be one of the most confounding questions of dressing. After black tie and what to wear to a job interview, it's the area that solicits most hand-wringing. Long or short? High heels or low? Tux or tie? Expanding your idea of cocktail style will take the stress out of what to wear. A basic black and white dress or a more colorful one, jersey or velvet, is a smart start to an alternate look. Add a sexy, cowl-neck top in chiffon, a pair of strappy, black stilettos or cute, dressy flats. Make jewelry a reliable part of your wardrobe. Have fun and enjoy your cocktail!
