Pippa Middleton Looks Chicer Than Ever While Celebrating Her 33rd Birthday

Pippa Middleton is celebrating her birthday in style.

The royal-in-law turned 33 years old today, and she was spotted hitting the streets in London today wearing a chic monochrome ensemble to mark the occasion.

For her special day, the Duchess of Cambridge's younger sister turned heads in a silk blouse featuring a bow at the neck and a coordinating beige blazer. She paired the sharp pieces with a pair of matching cropped trousers. The author and super sportswoman topped off her outfit with leather trimmed wedge heels, a bright orange AEVHA London tote bag, and sleek tortoiseshell sunnies. The brunette beauty styled her locks in signature voluminous waves and kept her makeup to a minimum. Her dazzling engagement ring finished off her winning look.

And Ms. Middleton has plenty to be excited about. The street style star is currently planning her wedding to financier James Matthews—the duo announced their engagement back in July.
