I always like it when these two ladies get together — FLOTUS Michelle Obama and the British PM's wife, and head of the British Fashion Council, Samantha Cameron. You always know there are going to be some stunning fashion moments. I mean, SamCam arrived off the plane wearing a classic Burberry mini trench. Perfect to fly the British fashion flag and perfect for the occasion.

She stripped it off to reveal a Roksanda Ilinic pink silk blouse, which she belted over her navy trousers. She added some nice navy heels from Next, a high street brand. Mrs O wore a beautiful mustard yellow cardigan from L'Wren Scott and paired it with great wide leg trousers and her usual Jimmy Choo heels.

Later they attended another function where SamCam wore more Roksanda Ilinic off the peg, and Michelle wore Zac Posen dress and jacket.

Last night was the big State Dinner, to which Samantha Cameron wore a Alessandra Rich print dress with a high neck and bow while Mrs O wore a Marchesa dress — an nod to the British designer who lives in the US. Both ladies looked amazing.
