Pippa Middleton Hits Up London In A Sophisticated Look (PHOTO)

As the younger sister of the Duchess of Cambridge, Pippa Middleton definitely doesn't have to dress as elegant as Kate Middleton does, so we're used to seeing her in sexier and more casual looks. But it looks like Pips decided to smarten up a bit while running errands in London on Tuesday.

After spending a night clubbing with her sister and brother-in-law Prince William last week, the 29-year-old hit up London during the daytime in a silky plum blouse, black pencil skirt and oversized shades (her signature) with a laptop and satchel in tow -- quite a corporate look for the socialite.

It's not like Pippa doesn't have a job though. She works for her parents' party-planning company, and she's just penned her own book on the subject Celebrate (but, in light of her sister's photo scandal, she's reportedly declined to do a book tour following its release this month).

Whether or not the duchess' little sis was heading work, we think she's doing well in the style department these days. The makeup seems to be at a minimum, which isn't always the case, and she looked pretty smart while apartment-hunting in New York City (and shopping around for a boyfriend, according to rumors). So maybe Pippa's gearing up for a big stateside move complete with a more streamlined wardrobe?

We'll have to wait and see about that. In the meantime, what do you think of Pippa's outfit from yesterday? Couldn't you just see her strutting down the streets of the Upper East Side?
