Kate & William Party at Bunga Bunga Bar

The Duke and Duchess of Cambridge had a night off from parenting duties, to celebrate the birthday of Louise Aubrey Fletcher, wife of one of Prince William's oldest friends, Harry.

They revelled till the early hours at the exclusive Bunga Bunga bar in London.  At the end of the evening the royal couple were escorted through a side door back to Kensington Palace.

Kate kept warm in her black Temperley 'Odele' coat.  The £1,960 sheepskin jacket features an asymmetrical zip front with genuine  leather trim detailing and gold metal hardware.

Kate wore a black printed dress which is reminiscent of the Issa bird print dress.  It's hard to ascertain the style of the dress from the limited photos, but it's unlikely to be the Issa dress because this style appears to be shorter. Furthermore, the Duchess no longer wears Issa since the label was bought by Camilla Al-Fayed, the half-sister of Dodi Al-Fayed.

Kate carried her black leather Mulberry Locked Cosmetic Purse.  Kate has owned this purse since 2011.

It's difficult to distinguish, but it appears that Kate is wearing her black suede Episode 'Angel' pumps.
