The 37-year-old television personality has taken to social media to prove she has not thrown out a pair of Gucci open-toed heeled shoes, which she wore to the formal end of year ceremony over 20 years ago.

The brunette beauty - who has sons Mason, seven, Reign, two, and four-year-old daughter Penelope with her on/off partner Scott Disick - shared a picture of the designer brand of footwear on Snapchat, which she captioned: "My prom shoes from high school (sic)."

Although the 'Keeping Up With the Kardashians' star has failed to explain why she has kept hold of the item for over two decades, her recent [post has set tongues wagging she has treasured the item so she can show them off to her children when they grow up and let them wear the shoes if they fit into the product.

Meanwhile the oldest of the Kardashian/Jenner brood regularly receives beauty advice from her 61-year-old momager Kris Jenner, who has told her to "always" treat her skin like silk if she wants to boast a flawless complexion.

Speaking previously, the reality star said: "My mom always says to treat your skin like silk. In with @manukadr Cashmere Touch Cream... Enriched with a blend of oils, Purified Bee Venom and Manuka Honey, which makes skin feel like silk too. #ManukaAmbassador (sic)."

And Kourtney - who was announced as Manuka Doctor's global brand representative in April last year - "loves" the Replenishing Oil from the natural cosmetics company because she has claimed it "protects" the moisture levels in her skin.

She explained: "One of the many reasons I love the Replenishing Oil from Manuka Doctor is that it helps protect the moisture levels of my skin so that it looks and feels more silky and smooth. I love to apply it to my neck & décolletage too! Join me tomorrow as I takeover @manukadr Instagram! #ManukaAmbassador #KourtneyTakeover (sic)."
