Well Pippa hit the opening of the first London store of Tabitha Webb, one of her favourite designers (pictured above).
And, of course, she sported one of Tabitha's creations - the spot-print 'Twiggy' dress, (£435), which she paired with a black waist belt.
Pippa added a slightly tougher edge by finishing with flat suede ankle boots instead of glamorous heels, and also carried a suede studded envelope clutch.
Tabitha's label is also loved by stars like Miranda Kerr, Emilia Fox and Emmy Rossum, and her Elizabeth Street store in Belgravia is likely to be frequented by a host of celebs.
Pippa worked her usual heavy eyeliner, which looked pretty with her tan from a recent trip to Italy with her boyfriend Nico Jackson.
The royal-in-law has been keeping herself busy with public engagements, and let her hair down at the Invictus Games with her brother James. Earlier in September Pippa attended a wedding in Italy to see Charlie Gilkes and Anneke von Trotha Taylor tie the knot.
It was recently announced that Pippa is set to become an auntie for the second time, as sister Kate his expecting her second child with Prince William. So Pip must be cramming as many public appointments in as possible before she's called upon to help with the babysitting...
