Strapless neckline gowns are a highly sought-after choice when it comes to prom dresses. Whether you prefer a long, more formal dress or one with a hem line that hits just above your knees, a strapless neckline gown instantly adds an element of classic beauty. With several subcategories, finding the right strapless neckline dress is easy. Straight necklines are ideal for smaller-boned women while those necklines that are heart shaped accentuate a bigger chest. Those dresses that have a slight curve, either upward or down, to the neckline add more interest for the eye. Strapless dresses also provide a flawless background for your favorite jewelry. Keeping your hair off your neck and shoulders helps to accentuate the structure of your face in a timeless, classic way.
