British Invasion!

London-based women's wear designer Jenny Packham is making a huge splash across the pond.

The designer is renowned for her jaw dropping evening and cocktail looks. Fans of the line include Sarah Jessica Parker, Halle Berry, and Beyonce just to name a few. But recently,its the young Hollywood set that is falling in love with Packham's designs.

Just this weekend Ashley Tisdale wore an amazing silver cocktail number to the “High School Musical 3” premiere at the Rome International Film Festival... and not to be left out Katharine Mcphee rocked an open back gown to the Carousel of Hope ball over the weekend in Beverly Hills.

The dress is from Packham's Fall 2008 catwalk collection. After taking a look at some of her creations its no wonder Packham is becoming a British invasion on almost every red carpet.
