Oops! Jennifer Aniston Leaves the Sales Tag on Her Outfit

Was the Office Christmas Party star planning to return the Céline blazer?

Even Jennifer Aniston is susceptible to the occasional, accidental fashion faux pas.

Paramount Pictures, The Cinema Society and Svedka hosted a screening of Office Christmas Party at New York City's Landmark Sunshine Cinema Monday night, where Aniston turned heads in a Brandon Maxwell jumpsuit and Fred Leighton jewels. Designer Brandon Maxwell praised her on Instagram, writing, "One of my favorite pieces on one of my favorite women!"

But after she posed for pictures with co-stars Jason Bateman and Olivia Munn, Aniston put on a coat to brave the winter weather. Unfortunately, she didn't realize that her black satin Céline blazer still had the sales tag on. (For those who are curious, Aniston wears a European Size 36.)

Oops!

It's unknown whether Aniston was planning to return the jacket at a later date or if she merely forgot to remove the tag before deciding to wear it. Either way, it's almost guaranteed that Aniston (or, let's be real, her assistant) will be double-checking her outfits from today onward.

And honestly, who hasn't worn something with the tags still on—intentionally or not?

Aniston's rocked a number of ensembles while promoting Office Christmas Party. The actress describes the star-studded movie as a "big, fat laugh" in Marie Claire's December issue, "which is so nice after all these superheroes and sequels. It's fun to throw in a little popcorn comedy."

For Bateman, the main draw was reteaming with Aniston. "Anytime I work with Jen or hang out with her, there's that incredible spirit of hers, and it's infectious. When you do a comedy, you really want to feel safe you can make a fool out of yourself, and she permeates a set with so much good spirit and ease," the actor says. "It's amazing to see what she brings out in people."

Office Christmas Party is in theaters Friday.
