Olivia Culpo gets asked to 'put a blouse on' before boarding American Airlines flight with friends

Former Miss Universe Olivia Culpo has slammed American Airlines after staff told her that her traveling outfit was 'inappropriate' and demanded that she put on a blouse over her crop top and bike shorts or risk being banned from her flight to Mexico on Thursday. The 29-year-old flew to Cabo with her boyfriend Christian McCaffrey and her sister Aurora - who shared details of the incident on her Instagram Stories Culpo, a former Sports Illustrated Swimsuit star, turned up to the airport in a black cashmere sports bra, matching biker shorts, and a long black cardigan, before being told to cover up The model re-posted her sister's videos on her own account, questioning why her outfit was deemed 'inappropriate' or 'offensive' by American Airlines staff To add insult to injury, after Culpo covered her ensemble up with a large hoodie that she borrowed from her NFL player beau Christian McCaffrey, she and her sister came across a fellow passenger who was also wearing a similar athleisure look, which had not been flagged by American Airlines staff. 'Get me to Cabo': Culpo's sister Aurora insisted that the model 'looked cute' and 'appropriate', voicing her confusion over the airline's decision to make her cover her outfit In order to board the flight, Culpo covered up her outfit with her NFL beau Christian McCaffrey's hoodie However, Culpo and her sister expressed further shock and outrage after finding another passenger who was also wearing a sports bra, but had not been told to cover her outfit The unnamed woman voiced support for Culpo, noting that her own outfit was more revealing because her 'titties were out' After boarding the plane, Aurora shared an image of Culpo's boyfriend with his arms tucked inside his white T-shirt, joking that the football star was 'freezing' because he'd had to hand over his sweatshirt to his girlfriend. Culpo's furious sibling then shared a tongue-in-cheek post featuring the different elements of her sister's ensemble, all of which were from Naked Cashmere, while branding it a 'get kicked off American Airlines starter kit'. After boarding their flight, Aurora shared a picture of Culpo's boyfriend McCaffrey with his arms inside his T-shirt, joking that he was 'freezing' because he'd lent the model his hoodie The sisters continued to mock American Airlines on Instagram, with Culpo joking that her 'next airport look' will resemble the airline's staff uniforms from 1981 while Aurora posted details of her sibling's outfit, joking that it is a 'get kicked off American Airlines starter kit' Upon their arrival in Mexico, Culpo returned McCaffrey's sweater to him, while joking that she was 'dressed back in her risque athleisure outfit' Prior to the airport incident, Culpo took to Instagram to share an image of herself, boyfriend McCaffrey, and her sister, joking that her sibling was tagging along on their 'romantic' trip She went on to post a vintage image of American Airlines staff from 1981, in which they are seen sporting very conservative uniforms, cheekily writing that the full-coverage ensembles were her 'next airport lewk'.
