There are just some famous faces who carry a little more weight when it comes to determining which pieces, trends, and designers are in or out in the style world. I'm talking ladies like Cate Blanchett, Beyoncé, and even (or especially) the Duchess herself, Kate Middleton. So when Kate the Great decides to make a very public arrival wearing a particular designer, it's pretty clear the designer is both in demand and totally of the moment.

That was definitely the case Wednesday when Middleton landed in Australia as part of the royal duo's multi-week trip Down Under sporting a brilliantly yellow Roksanda Ilincic dress. With its square-cut neckline and chic white panelling, the dress was a reminder of the beautiful color blocking Ilincic is known for, as well as the fact that she's the designer to wear right now. Don't believe me? Just take these 10 famous fans as all the proof you need.
