White tie affairs are very formal and it is traditional to wear a long evening gown. Cocktail dresses are appropriate for black tie affairs. If the event is either white tie or black tie you can wear a dark color cocktail dress with dark stockings and heels or a long dark color dress with a straight skirt and high heels. Dark colors are appropriate for both black or white tie affairs and dark colors will give you a taller and slimmer look.
The Little Black Dress, The Wardrobe Essential
“The Little Black Dress” has been described as sophisticated, sexy, provocative, chic, elegant, practical, seductive, correct, and ageless. The fashion designer, Christian Dior, said ” You can wear black at any time. You can wear it at any age. You may wear it on almost any occasion. A little black frock is essential to a woman’s wardrobe.” What’s great about “The Little Black Dress” is that it looks fabulous with or without jewelry. You can wear a scarf with it for an interesting effect and it doesn’t show dirt if you take it traveling. In addition black is slimming so you’ll look a few pounds less when wearing it. * The Duchess of Windsor
