You're never fully dressed without a smile...or great accessory. See which celebs were showing of their statement pieces this week!

Ask any style editor and they’ll probably tell you that no outfit is complete without some great accessories. Whether it’s a statement necklace, a fun pair of shoes or a vintage piece from your grandmother, these items can make an ensemble. And apparently, no one knows that better than your favorite stars, who took to Instagram this week to show off their best new gets.

To celebrate the end of filming for Pitch Perfect 2, Anna Kendrick gave all of the Barden Bella actresses a Monica Vinader Fiji Diamond chain friendship bracelet. The one she shared was engraved ‘Crazy Youngster’ and we’re intrigued to know what the other ones said (and when we can expect ours in the mail).

Kourtney Kardashian showed off a couple Woven Play feather headbands that we can only assume are for Mason and Penelope when they want to look boho chic (so, always). She also snapped a shot of a metallic Lego-man necklace that she got from Scott — and knowing him, we wouldn’t be surprised if it was real gold.

“I’m feeling monograms right now,” captioned Mindy Kaling on her shot of her initials-emblazoned Louis Vuitton bag. “They’re a nice blend of summer camp practicality and staple of WASP prissiness.”

Normally, we wouldn’t consider wearing baseball caps, but after seeing this sparkly Patricia Field ‘Vogue’ snapback on Lena Dunham, we might take a chance at ruining our blowout for this.

Leave it to Diane Von Furstenberg to mix function with fashion so effortlessly. While the designer was touring a building site, she donned a stylish hard hat that almost makes us wish we were adept at construction so we could wear one of our own.

Slip-ons are a staple comfort shoe in our closets and we were super envious when we saw the Givenchy pair that Jared Leto received as a gift from his brother. The last thing our brother gave us was a noogie/headlock combo.

Considering that Kim is besties with Givenchy guru Riccardo Tisci, it’s no surprise that her momager Kris Jenner was rocking a pair of the line’s sunglasses for a day at Disney World.

No, the S necklace is not for ‘Swift,’ but rather ‘Selena.’ Taylor showed her newly 22-year-old bestie Gomez some birthday love by wearing the gold necklace with her initial.

We can always count on our Style Council member Ashley Madekwe to share a picture on her Instagram that has us double-tapping at lightning speed, and these Senso leopard flats are no exception — we’ll gladly take the jeans and black crossbody as well.
