Kate Middleton little sister Pippa Middleton looked as stylish as possible seeing as she had to dress appropriate for an event that the Queen would be attending.

The Vanity Fair columnist was spotted at the christening of her 3-month-old baby nephew Prince George on Wednesday, October 23rd.

Nico Jackson's girlfriend was accompanied by her parents and brother James and wore a cream-colored, wool trapeze coat as she entered St. James's Palace, according to Us Weekly.

Underneath the coat Middleton chose to wear a lace "warm, blush oyster" hued shift dress that featured a high neckline with sheer panels.

Both coat and dress were designed by British couture designer Suzannah Crabb, who has in the past styled the 30-year-old from head to toe.

Prior to the christening Pippa Middleton has wore several creations from the designer including some of her most memorable looks including an emerald silk crepe dress which she wore to a wedding in September 2011.

Crabb said, "She phones first but just turns up on her own." Since styling the Duchess of Cambridge's little sister the designer has felt the benefits from the "Pippa Middleton Effect."

For shoes Kate Middleton's little sister wore Emmy and a clutch with a bunny clasp from Wilbur & Gussie.

According to Crabb, creating Pippa's christening outfit required hours of research. She explained, "The outfit had to be both beautiful and appropriate from the length of the hem, to the style of the millinery and the subtle color and cut."
