Olivia Culpo asked by American Airlines to put on a blouse ahead of flight

Olivia Culpo almost missed a flight to paradise after American Airlines found her outfit to be inappropriate.

The former Miss USA was boarding a flight to Cabo San Lucas, Mexico, when her sister, Aurora Culpo, revealed that she was told to "put a blouse on."

"Olivia and I are going to Cabo and look at her outfit," Aurora says in an Instagram Story, while showing off Olivia's attire, which consisted of black biker shorts, a black bralette and a black coverup.

"She looks cute. She looks appropriate. No. They call her up to the desk and tell her that she needs to put a blouse on otherwise she can't get on the plane," Aurora continues. "Tell me that is not so f---ed up. American Airlines, I love you so much, please get me to Cabo."

Olivia shared her sister's video, writing, "Oh no I'm confused lol. Is this inappropriate/offensive? Leave it to aurora to cause a scene. Hide me," she wrote.

In a follow-up video taken from the airport, Aurora shows off another passenger who is wearing a similar athleisure outfit to Olivia's. "That's weird," the passenger said about the fuss over the model's look.

The Sports Illustrated Swimsuit cover model ended up wearing her boyfriend Christian McCaffrey's sweatshirt. Aurora later shared a photo of McCaffrey struggling to stay warm on the plane in just a T-shirt. She captioned her Instagram Story, "When you freeze bc ur lady dress inappropriate AF. Exactly how Jack from the Titanic died."

The jokes didn't stop there. Aurora trolled the airlines when she shared a screenshot from a website consisting of similar clothing Olivia was wearing. "Get kicked off @americanair starter kit," Olivia's sister joked.

After the three landed in Mexico, Olivia assured her followers that she was "dressed back in my risque athliesure (ic) outfit and gave Christian back his clothes lol."
