For whatever reason, Pippa Middleton seems to always steal the spotlight at other people's weddings.

More than a year after her older sister, Kate, and Prince William tied the knot, the British party planner, 28, looked ravishing in red at Camilla Hook and Sam Holland's nuptials in East Lothian, Scotland Saturday.

Pippa's raspberry wrap dress looked reminiscent of the navy Issa design Kate, 30, wore when she announced her engagement to William, 29, in November 2010. For Saturday's ceremony, she wore an intricate fascinator featuring three red roses and a black veil.

The Celebration author, who attended Hook and Holland's wedding with a female companion, completed her look with black pumps.

In April, William's sister-in-law was involved in a bizarre gun controversy -- giggling in an Audi convertible in Paris as the driver waved a semiautomatic pistol at a photographer. "This is embarrassing for them," a royal source told Us Weekly, who added that the event had "put Kate in a very difficult position."

Since then, Pippa has maintained a relatively low profile -- something she hadn't been able to do since her sister's April 29, 2011 wedding. "Kate feels guilty Pippa can't just slip back into normal life," royal watcher Katie Nicholl told Us.
