Pippa Middleton Breaks All The Royal Rules In Sexy Sheer Dress

Pippa Middleton ensured all eyes were on her at the Sugarplum Ball when she stole the spotlight in a daring see-through dress

Pippa Middleton was the belle of the Sugarplum Ball last night when she sauntered into the exclusive London event last night in a daringly sexy sheer gown.

The 30-year-old sister of the Duchess of Cambridge braved the crisp winter weather and opted for a black floor-length dress with intricate embroidered lace detail and a see-through fluted skirt.

Expertly showcasing her slender frame and toned legs while still managing to maintain her oh-so-elegant edge, Pippa and her world-famous figure made their dramatic return to the party scene in real style.

Kate's stylish younger sibling teamed her vampy frock with a matching black cropped sequin jacket and black heels, keeping her hair and make-up simple with a coiffed updo and a hint of black eyeliner and blush.

Pippa's racy choice of gown wasn't the only reason all eyes were on her and her date last night, either. The petite brunette also set tongues wagging by parading her handsome plus one, boyfriend Nico Jackson.

The pair have been spotted out and about together at several exclusive London events over the past few months, but it's rare that we get to glimpse the well-suited couple doting on each other so publicly.

Pippa and Nico looked the picture of happiness as they cosied up in front of the cameras at the glamorous West London event.

But despite rumours that the duo are set to be engaged, a sparkling rock was noticeably absent from Pippa's ring finger.

Looks like we'll be waiting a little longer before we see Kate repaying the favour and escorting her sister up the aisle...
