Ashley Tisdale stepped out in one of Jenny Packham’s glittering gowns from the spring/summer 2011 collection at the Elton John AIDS Foundation Oscar Viewing Party in February.  The High School Musical star’s dress had a similar asymmetrical neckline and cinched waist, but less crystals and sequins than Kate’s glistening gown. The 25-year-old’s Tisdale’s sleek half-pony and satin clutch gave the 5’3″star a sophisticated edge.

Raining in sequins and fabulously figure-hugging, the Duchess of Cambridge’s adaption of the Jenny Packham gown was fit for a princess. Kate paired her beautiful glimmering dress with LK Bennett shoes, a rose clutch and, of course, her handsome prince.

Sandra Bullock showcased a powder pink one-shoulder crystal-encrusted gown Jenny Packham gown at the Golden Globes this year, but while the Blind Side star’s dress was stunning, her heavy, dark bangs ruined the glamorous look.
