Kate Middleton Shows Some Skin At Kensington Palace Ceremony

Kate Middleton's such a rebel!

On Wednesday, the Duchess of Cambridge showed off some skin while hosting guests at Kensington Palace for an awards ceremony. The pregnant duchess, who is expecting her second child next April, looked gorgeous in a black belted Hobbs top with a sheer polka-dot neckline and sleeves and a knee-length Jenny Packham skirt. The Duchess styled her brunette locks into a sleek half updo.

The princess welcomed mental health charity Place2Be—of which she has been a patron since 2013—for the inaugural Wellbeing in Schools Awards, where she was scheduled to meet with the 20 award finalists.

In a forward to the evening's main event, the 32-year-old mom said:

"It is wonderful that this important area of children's emotional health is being recognized with these inaugural awards. The commitment, dedication and hard work that is going on across the schools involved with Place2Be is truly humbling."

The Duchess has been hard at work since returning from bed rest because of her debilitating morning sickness. In the past few weeks, Prince William's other half has showed off her ever-evolving style in a chic blue Alexander McQueen coat during a visit to the Valero Pembroke Refinery and in a princess-worthy lace gown at her first Royal Variety Performance in London.

Next up for Kate and Will is a trip to the U.S., where they will be spending three days touring New York City and Washington, D.C. in December.

Kate's had quite the year:
