To give you an idea of what the trend is today, follow the stars. Typically the manufacturers are showing what the celebrities are strutting on the red carpet or the award ceremonies, following the stylish stars as well as the couture industry.

The most important factor is to keep your figure and personal style in mind. Although certain styles will work for everyone, your body plays a crucial role in choosing the perfect dress that flatters your figure. Accent your favorite body part and flaunt your looks. Remember you can look fabulous without revealing so much. Too much of anything is no good and you want to look classy not trashy. Less is always more.
Style. A fitted dress will show off an hour glass figure. A cocktail dress, a few inches above or below the knee, will feature your great legs. A ball gown skirt will camouflage your back side, large or small. Always create balance so your top and bottom appear to be in proportion.
If you tend to be on the sophisticated side, look for a simple black column dress or an elegant cocktail length with simple accessories to highlight your face. If preppy is more you, look for a bold black and white using a pop of color in your shoes and handbag. If you like looking different or showy, don’t go over board. You may want to stand out but be sure it’s in a  good way. If you are going for short or a high split stay away from cleavage. Think modest, it’s a school prom not a Vegas show.
Accessories. A very intricate style calls for minimal accessories. Keep your shoes and handbag simple. To make a bold statement play up the eyes or lips to add drama and couple it with sheer make up. Be sure you are able to walk in the shoes you select. If you are not used to wearing heels choose a lower heel or practice walking in a higher heel. You want to be able to walk with poise and confidence. That’s the secret to looking beautiful.
Color is another important factor. Pale colors will wash out ivory skin but the deeper shades of pink, peach, or lilac are great for light completions. Usually black works for any skin tone. Jewel tones work best for darker skin tones. If you want to be daring with color, keep the style simple.
Determine your budget. More expensive is not necessarily the answer to looking great. You don’t have to break the bank for a fabulous style nor do you have to sacrifice style for price. Give yourself time to shop around and use some creativity. Shopping on line will give you an idea of what’s out there before you hit the stores. Be sure to wear a good bra, shape wear, if necessary, and a pair of heels when going shopping. If the dress is going to require a lot of alterations it’s probably not cut for you. You don’t want to pay more for alterations than the cost of the dress. You’re likely to never wear it again. Save the alteration money for when you want to cut it down.
Once you decide on a color, inform your date so you don’t clash in color and style. For example, you don’t want him in a contemporary look while you are wearing a Victorian style. You want to compliment each other so guide him a bit especially if fashion is not one of his strengths. Be sure to compliment him.
Enjoy yourself. Don’t stress out too much. When shopping, just bring one person you trust with a sense of style. Too many opinions will confuse you and it is rare that someone wants you to look better than they do.
Decide which styles will flatter your figure, decide on your budget, give yourself enough time to shop, and more importantly have fun. You want it to be a memorable event and a great way to bond with your mom, sisters or a good friend.
