Pippa Middleton kate Middleton dress book signing heels

She's making her rounds!

On Tuesday, Pippa Middleton looked simply gorgeous in a purple dress when she attended the launch party for her book Celebrate: A Year of Festivities for Family and Friends at De Vries Boekhandel in Haarlem, Netherlands.

The 29-year-old sister of Duchess Kate Middleton was all smiles at the event despite her busy schedule. Between visiting her sister who's in the hospital for acute morning sickness and attending weddings in Ireland, it's amazing how she's able to handle it all!
