William And Kate Join Pippa Middleton And Princess Eugenie On Mayfair Night Out

Who? The Duke and Duchess of Cambridge, Pippa Middleton and Princess Eugenie

What? A right royal knees up. The Duke and Duchess hit Lou Lou's Private Members Club last night, along with Pippa Middleton. Surprisingly, Kate wasn't wearing a belted coat, probably because she'd lent her latest leather accessory to her sister. Princess Eugenie also showed up in a belted, burgundy dress, after dropping in on the Contemporary Art Party earlier in the evening.

Where? Mayfair, London, 10 October

Verdict? How does Kate's sleek all-black style compare with her plum-coloured ensemble from her daytime engagement? Let us know in a comment and see more of the royal couple below:
