Color choices are broad and sparkle is always welcome.
Expanding your idea of cocktail style will take the stress out of what to wear. A pair of basic black pants in wool, jersey or velvet, is a smart start to an alternate look. Add a sexy, cowl-neck top in chiffon or metallic jersey, a pair of strappy, black stilettos or cute, dressy flats.
If serious business is at hand, a fitted jacket in a jewel tone like ruby or in black covers all bases. Also try a boat-neck, jersey blouse or soft, wrap top a la Diane von Furstenberg.
Men are safe with a sports-jacket-and-slacks combo.
However, a dressier approach- is welcome. With the exception of hardcore business cocktails - say, cocktails before a business seminar - do not wear the exact same suit, shirt and tie that you wore to work. Remove the tie or substitute a silk, knit shirt for workplace button-down shirt and tie.
Jazz up a suit with a pastel shirt and pastel tie. Heck, skip the tie all together and experiment with a printed or colorful, striped woven shirt.
It's not unusual for cocktails to be held outdoors on a rooftop garden, by a hotel pool and so on. For men, it's easy, a jacket - preferably a 2-button or 3-button. A pullover sweater may already be part of cocktail dress. For a woman, cool nights call for a chic cover up like a fur shrug or a capelet in wool or satin. Drape a large scarf or a huge swath of gorgeous fabric around your shoulders for a touch of glamour.
A small fitted cardigan is fantastic with a full skirt or over a vintage-style dress. Add a jeweled or flowered brooch for extra interest.
Make jewelry a reliable part of your wardrobe. However, avoid the goosy idea that jewelry alone will miraculously transform an outfit from work to cocktails.
Not true. You must have a festive outfit together, and then accessories can do the job of brightening.
On the subject of accessories; nothing ruins a cocktail look quicker than a big work-a-day purse. There are a few instances where a large pocketbook - like a metallic hobo - will meld with a gutsy dress. But the no-brainer is to go with a mini clutch every time. And who wants to use more brain cells than they really have to.
