Hilary is wearing a pair of Yves Saint Laurent "Hamptons" Platform Sandals, which reflect the signature style of the YSL shoe. What I love about the shoes are the rope detail and the beautiful creamy brown colour of the leather.
The shoes are the perfect choice to glam up any casual outfit, which is exactly what Hilary Duff has done. It's been a while since I wrote this post, and the shoes are no longer available but for a similar style (in black) click here and click here to visit the official site to find out more about YSL and to shop the collection.
Side note: Hilary Duff is wearing a Louis Vuitton Neverfull GM – Timeless tote.
