Important News: Kate Middleton Just Wore This Famous Designer For the Very First Time

"Hmmm, seems very familiar," was our first thought when we saw Kate Middleton's purple skirt suit set. Upon closer look, however, the Oscar de la Renta outfit is actually brand new and the first Kate's ever worn from the fashion house, though we get why the top-and-skirt combo resembles so many of her past outfits. Kate has a penchant for Peter Pan collars, button tops, and matching sets; she knows her signature style and sticks to it. The fact that she debuted an Oscar de la Renta look, however, is both fresh and exciting.

The duchess of Cambridge is also in good company, as the designer has dressed everyone from Amal Clooney to Michelle Obama. It seemed the duchess wanted to try something new, and Oscar de la Renta is not a bad choice to make. Read on to see Kate wearing the designer for the first time, because we certainly hope it's not the last.
