Catherine Walker

With thrift in mind, Kate sometimes recycles clothes, like this blue Stella McCartney dress and this lemon broderie anglaise dress.

The late Catherine Walker was one of Diana's most influential designers.

Her fashion house continued after her death in 2010, and is now favored by Kate.

Well, Catherine Walker's a really interesting choice for the Duchess.

Firstly, because Catherine Walker is synonymous with Diana.

She and Diana would work very closely on designing, a little in the same way that Sarah Burton and Kate do today.

But for Kate to go to Catherine Walker for, um, some really important dresses, I think, uh, is, is probably Kate's way of paying tribute to Diana.

So when we saw Kate coming down the steps of the plane as they landed in Wellington, um, not only was she in a fabulously vibrant red against this dreary, watery, wet sky, she sort of stood out with her pillbox hat, her dress coat.
