The Coachella Valley Music and Arts Festival is all about music, beauty and good vibes. Or, if you're so inclined, it's about firing shots at your old co-worker from hell.

Fashion designer Whitney Port, who spent the first season of "The City" as a Diane Von Furstenberg public relations associate, hit up the annual concert series this weekend, and between shows, she seemed to have gotten a bit nostalgic about her days at MTV -- all thanks to her jacket.

Yup, the bit of outerwear reminded Whit of one particular "City" episode in which she and co-worker Olivia Palermo were tasked with pulling a spring look for Jessica Alba's ELLE cover shoot, and though Whitney ultimately selected the winning piece, Olivia took credit during a meeting with DVF's top dogs. And you thought a long line at your office's coffee pot was irritating...

"I pulled this look. #thecity Who remembers this episode?! #whitneyeve" Whitney captioned the photo above in an epic poke-fun-at-my-past throwback shot. We can't confirm whether Olivia popped up to assume responsibility for Whit's 2015 look, too, but we're certainly not counting out the possibility. Where you at, Palermo?

Check out the classic "City" clip, sound off on Whit's look and tell us if you got a good laugh out of her joke!
