Sleek Evening Gown - A sleek evening gown can make you feel elegant, sexy, and regal all at once. A sleek evening gown makes the most of your figure and gives you a classic silhouette.  Jewelry choice should be still the best you own, and shoes should be appropriate to the dress. When dancing is a part of the event, do consider a sleek evening gown that will allow for this. Don’t wear a skintight sleek evening gown if you know you’re going to have to be moving.
