Celebrity Fashion: Hits and Misses of the Week (GALLERY)

Demi's Style Evolution
Demi Lovato's fabulous fashions through the years.
This week saw a lot of skin: plunging necklines, short hemlines, and high-slit dresses.

Stunning stars flaunted their goodies in show-stopping pieces as they got glammed up to make public appearances.

Fashion designer Whitney Port attended the Magic tradeshow in Las Vegas, appearing fashion-forward in her funky attire, and actress Ashley Greene looked flawless in a pink strapless gown as she promoted her new feature The Apparition.

Yet, other A-listers such as newly engaged Avril Lavigne were a complete fashion disaster.

Who dazzled and who disappointed in Tinseltown fashion this week?

One fashion mistake was made by actress Kirsten Dunst, who was spotted out in a frumpy blue dress that could have been confused for a trench coat, as she promoted her new flick Bachelorette.

But America’s Next Top Model host Tyra Banks was a sight for sore eyes as she attended a party in New York City for her hit show — donning a sleek black number, the model definitely worked it.
