Last night saw the return of our favourite princess, the Duchess of Cambridge as she attended her first official engagement since the announcement of her pregnancy. Now 13 weeks expectant, she was glowing and clearly over her antenatal sickness as she turned out looking very chic in a little black dress for the Action on Addiction charity gala at the award-winning L'Anima Restaurant in London. The cut-out style Termperley dress flattered her tiny bump to perfection as the detailing cleverly averted eyes to the sultry panel detailing. She kept things dark and paired her black dress with black heels and a black clutch, and as always her hair curled beautifully over her shoulders. Fancy a slice of Kate's stylish dress? If you love the style but fancy something a little more daring then we think our two Forever Unique dresses will do just the trick (far left and far right) both are perfect for the winter party months ahead. The Forever Unique Hollies Black Sequin Patterned Fully Embellished Dress, £410, would make a stand-out Christmas party dress with it's intricate embellishment, whilst the Forever Unique Jeannie Lace Dress in Black, £165 has stunning lace detail that's perfect for a dinner date or cocktails. Whilst if you're looking for something a little more demure, the knee-length lace Body Frock Natalie Dress, £255, is just the ticket for stealing Kate's classic yet sultry style.
