PICTURE EXCLUSIVE: Sheer genius! Kendall Jenner wears her bra OVER her tummy-flashing white crop top as she sports a racy lingerie look at London airport

Her sister maybe celebrating Scott Disick's birthday in a completely sheer lace dress but Kendall Jenner was protecting her modesty in a similar see-through black bra on Friday.

Dressing for an early morning flight, the reality TV star wore a white crop top underneath her bra so that she could tease her lingerie while narrowly avoiding a sartorial slip up.

Kendall, 20, was leaving London already, seen jetting out of Heathrow Airport little more than three days after arriving to promote her new collaboration with beauty brand Estee Lauder.

Layer your lingerie like Kendall Jenner in a lace bralet by Anine Bing

Fresh from promoting Estee Lauder's new super sheer foundations at Selfridges the previous evening, Kendall Jenner chose a barely there bralet by hip LA designer Anine Bing for the morning's airport run.

She gave her look a little more coverage though as she layered it over a white crop top. If you love the summer's lingerie trend but don't fancy leaving the house in just your bra then this could just be a look for your.

JW Anderson has championed the layered lingerie look for some seasons and although we may have balked at first we reckon now's the time to give it a try.

Preparing to spend yet more time in the air, the brunette made her best efforts to dress down for the flight.

Though for a Keeping Up With The Kardashians star, that included heeled latex boots and a must-have cape coat.

Making the most of her slender curves, the catwalk star also made a pair of ripped, high-waisted jeans look completely enviable.

While in town, Kendall has squeezed in time for a photoshoot, a plush dinner in the British capital and the glittering launch of The Estee Edit at Selfridges department store.

Yet across the pond, her sisters Kim, Khloe and Kourtney are gathering to celebrate Scott's 33rd birthday.

Practically a brother-in-law to Kendall, Scott is the father of Kourtney's children Mason, Penelope and Reign, and was the 37-year-old's long-term partner until the end of 2015.

Kendall is no doubt rushing back to celebrate the birthday with her mother Kris Jenner and little sister Kylie.

Though the most recent episode of KUWTK hinted that her busy, jet-set lifestyle as a model is putting distance between the supermodel and her big sisters. 

Capturing a tense lunch between Kendall and Kourtney in Sunday night's episode on E!, the Victoria's Secret Angel said: 'It really annoys me when you come to the city and don't hangout with me.'

Her business had obviously been misconstrude by her big sister, who later said in the confessional: 'It does make me sad to hear that Kendall feels left out. I just assume that she's having the time of her life.' 

Kendall also confided in her mother Kris about balancing her commitment to her career with home life: 'I don't want to be forgotten about because I have to work a lot,' she said.

Momager Kris was later heard encouraging the rest of the tight knit family to 'give [Kendall] extra love when she's back in town.'
