The royal beauty wore a simple, custom dress from the designer's pre-A/W 2012 collection. In a warm grey, the half-sleeved dress is demure, structured and conservative yet still retains personality.
The dress has a flattering peplum detail at the waist, and is accented with jewel mosaic detail at the cuff and neckline. Catherine wore a signature pair of LK Bennett pumps in forest green and a matching clutch.
It was a rainy night in London, but husband Prince William was nearby to shade the Duchess from the rain, wearing a navy two-piece suit, with single-buttoned jacket accessorised with a maroon, dotted tie.

Catherine wore her hair in a signature style of loose curls, with her shiny tresses looking as enviable as ever. Tomorrow marks the first anniversary of the pair's wedding in Westminster Abbey.
