Kendall Jenner goes braless and flashes her nipples in see-through jumper as she arrives at LAX airport

The supermodel kept her head down as she went braless

Kendall Jenner arrived at LAX airport today in a seemingly modest outfit of a long brown knitted skirt and matching jumper.

But as the cameras flashed, she unwittingly exposed herself, flashing her nipples.

The stunning supermodel went braless but was clearly wearing a thong to avoid ruining the line of her skirt.

She wore dark sunglasses and kept her head down as she got into a blacked-out car.

Earlier this week, Kendall showed-off her endless legs at the star-studded 10th Annual Veuve Clicquot Polo Classic.

The 21 year old was at the posh horse event held at Liberty State Park, New Jersey alongside a hole host of other celebs, including Nicole Kidman.

The Victoria Secret beauty made sure that all eyes were on her though, donning the short printed dress and white ankle boots.

She teamed this with some glamorous shades and handbag that matched her outfit at the Veuve Clicquot champagne-sponsored bash.

Kendall is the half-sister of reality TV star Kim Kardashian and shares both her parents with younger sister Kylie.

Just last week it was revealed Kendall and Kim are totally furious about what Caitlyn said about their mum Kris in her soon-to-be-released autobiography.

In clips from an upcoming episode of Keeping Up With The Kardashians , the sisters are seen looking extremely unhappy about the contents of Caitlyn’s new book.

In The Secrets Of My Life, Caitlyn – formerly Bruce – talks about her life-long struggle with gender issues, her life with Kris and the kids, and her transition.
