There are several dramatic elements in this evening dress that make it great for prom. It's in a fun bold color, a sexy fabric, and has a generous train. Plus a unique neckline.

Notice how Armani's angling of the neckline with an inverted 'V' shape at the bottom flatters January's mid-section, creating something of an elongating effect, sort of pulling up.

The silhouette for this lovely creation by one of Hollywood's favorite Italian fashion designers is wonderful. The dress has been expertly fitted. Falling just above the ground is perfect.
