Go on, guess
The Duchess of Cambridge attended the annual National Portrait Gallery gala fundraiser, looking stunning in a lace outfit with a special meaning.
Model and presenter Alexa Chung also attended the event, and we reckon she has something in common with Kate: they both looked like princesses on the night.
Alexa looked positively regal in her Loewe dress, an off-the-shoulder polka dot design featuring billowy sleeves and a full skirt, part of the AW17 collection. Trust her to wear something straight off the catwalk.
Like Kate, she kept the rest of her look minimal, sweeping her hair to the side and opting for natural make-up.
She accessorised with sparkly drop earrings and some simple black strappy heels, which offset the gown beautifully.
See? Who needs a crown to look like a princess? A designer dress will do the trick just fine.
