These Celebrities Had The Coolest Accessories Of The Week (PHOTOS)

This week, a few of our favorite celebs gave us a refresher lesson on getting dressed. Jessica Alba and Lily Collins taught us that's it all about the accessories.

Ashley Olsen's low-key (and comfortable) footwear alerted us to a new trend, mules, while Gwen Stefani proved that flat sneakers aren't just for the gym.

Check out the best celebrity accessories of the week!

Ashley Olsen's The Row mules



You heard it here first, mules are about to have a major moment. If Ashley Olsen is wearing them, then it must be true.

Khloe Kardashian's sunglasses and gold link necklace


Khloe looks like such a badass with her reflective sunnies, chain link necklace and burgundy lipstick. We'll definitely be copying this look.

Michelle Williams' Giuseppe Zanotti heels



There is no better way to spice up a LBD than with a pair of killer heels.

Jessica Alba's hat


We're so used to seeing fedoras in black and grey that Alba's bold blue hat stands out in the crowd.

Lily Collin's Diane von Furstenberg bag


Color blocking and animal print go so well with a neutral outfit.

Olivia Palermo's thin gold belt


Figuring out how to wear chunky knits is a challenge, as they often add a lot of bulk. But it appears as though Palermo has found the perfect solution: Belt it!

Gwen Stefani's Tory Burch sneakers



We're over the sneaker wedge trend. Now it's all about the classic high-top sneaker, and this Tory Burch pair is exceedingly cool -- we love that they're patterned.
