1. Decide on Formality: Usually the event invitation will clue you into the formality of the event, whether it's casual or black tie. But sometimes even that will cause confusion (short dress or long?)

In general, the later in the day the event (after 6 p.m.), the dressier. Long dresses are usually reserved only for formal (black tie) occasions.

While some fabrics are year-round -- silk, brocade, organza, jersey -- fabrics like velvet and gold spangles are best reserved for winter holidays.

2. Flatter Your Figure: The most important feature of your new dress is how well it flatters you.

Remember that darker colors and simple cuts (a sheath, an A-line) are the most flattering.

Show off your best feature. If you have gorgeous eyes, then play them up with beautiful makeup, off-the-face hair and jeweled earrings in a complimentary shade.

Not sure what your best asset is? Ask a friend or significant other. Or go to a store that sells special occasion dresses and enlist the salesperson's help.

3. Choose a Color: You could just wear a little black dress (classy, flattering and slenderizing), but why not explore some of the other dressy options?

Red, bold prints, even gold are dramatic enough for evening wear. Pastels, mid-range brights and soft prints look great for dressy day occasions.

Blue (from navy to royal), pink (from cotton candy to fuchsia) and white (from candlelight to cream) look great on almost everyone. Remember that the "Don't wear white to a wedding" wisdom is still considered a fashion don't by most women.
