Pippa Middleton's Fashion Week Debut Mistake [PHOTOS]

When the Duchess' younger sister attended the Temperley London show for London Fashion Week, Pippa Middleton made a mistake by wearing a short dress.

Royal family followers might be excited to see Pippa Middleton on the front row of Temperley London's spring/summer 2012 collection, but fashion experts concurred that Pippa indeed made a huge mistake by wearing a short dress. Some photographers are claiming that the Duchess' younger sister's dress was too short that when she sat down, her underwear was showing. To keep her intimate wear from being exposed to hundreds of photographers, Pippa painstakingly clutched her hands on her lap so her satin dress won't run upwards.

Pippa wore a dress by the Temperley London, which has a decent length if she is on her feet. Since Pippa claims she is in no need of a stylist, the Duchess' younger sister must have overlooked this detail since it is her first time to attend such a high fashion event. Pippa sat next to Hollywood actress Rosario Dawson, who wore a long, loose, lace dress from the same designer.

Meanwhile Temperley London's designer, Alice Temperley, has only praises for Pippa's older sister, Catherine. In a report, Temperly is more than happy that the next Queen of England is a fashion fan.

"I think she's brilliant, she's brilliant for England. Perfect, perfect future Queen, she's elegant, she knows how to hold herself," told Temperley in a report.
