By now, Kate Middleton is likely used to making history: her every move, from her wedding to all those royal tours [1], will be remembered or reflected on forever — so naturally, she can't wear any old thing. For a trip to the Netherlands, Kate opted for a baby blue peplum and belted suit by Catherine Walker, accessorizing with beige pumps and a beige clutch. This sweet yet powerful look will no doubt be an iconic one later on: this is the duchess's first appearance overseas without Prince William.
