The Keeping Up With The Kardashians star has been hot property on the fashion scene recently, so it's hardly surprising she made an appearance at the highly anticipated show.
Model Kendall kept her outfit simple, rocking skin-tight leather trousers paired with pointed black boots.
She also covered up in a long, loose-fitting top complete with leather sleeves and an asymmetric hem.
Pretty brunette Kendall - who is rumoured to be dating Harry Styles - opted for low-key make-up with lashings of mascara, barely any cheek colour and a nude glossy pout.
And while we're used to seeing Kendall looking polished to perfection, this time she sported messy bedhead tresses and bare nails.
Her only accessory? A sultry model pose, of course!
Despite being just 18 years old, Kendall already has friends in high places in the fashion industry.
She was invited to grace the FROW at the event alongside Vogue boss Anna Wintour, Mr Topshop himself Sir Philip Green and style icon Kate Moss (who wore a khaki boiler suit, £68 from Topshop).
Reveal's Associate Editor Wendy Rigg, who attended the event, says: "Topshop Unique showed in Tate Modern, and any lucky members of the general public who were in the area got to see the show too, as Topshop aimed to 'democratise fashion'. Excitement was in the air as Kate Moss arrived with her little sister Lottie, who's signed to the same agency as she is.
"Also in the FROW was editor of American Vogue, Anna Wintour, Sir Philip Green, Kendall Jenner (yes an ACTUAL Kardashian sister – the young cool one of course), and Daisy Lowe."
"A generous 'packed lunch' was laid on for guests – and we loaded Topshop branded brown paper bags with posh sandwiches, mini quiches, brownies, cookies and fruit. Yes fashion folk do eat, although I didn't see Mossy chowing down! All washed down with champagne, of course.
"And the clothes? Well they were fantastic – and I for one wish I could wear them now. Layering, prints, texture and the addition of delicate sheer printed chiffon or sections of lace made for a super-modern take on winter. I loved the blue mohair belted coat and pencil skirt which opened the show.
"Models had straight hair and nose rings. Gold and yellow brightened up the winter palette, as did shades of misty blue. Throw in some snakeskin – a mac, structured sweatshirts over sheer, a knitted cropped sleeveless vest top layered over wool, and you've got a very edgy cool collection. I just LOVED it," says Wendy.
Kendall was later sported trawling the rails at All Saints in Spitalfields, London, sporting the same head-to-toe black getup.
She swept her hair back with a pair of sunnies while toting THE cutest handbag ever - a teeny tiny Céline Luggage Tote. We want!
