We've known Kate Middleton to come up with many nifty hacks, from recycling her outfits to how she hides her bra straps and VPLs.

And another centres around how the Duchess stops her shoes and tights from slipping, and it's quite the trick!

Kate, 39, can often be seen donning stylish outfits while out and about, and no stone is left unturned when it comes to the attention to detail put in to each outfit.

As a result, she's even thought of a way to stop her tights from slipping – by using sticky pads on the bottom of her feet so they stay in her shoes no matter what. Genius!

In the past, the mum-of-three was seen sporting some John Lewis tights with a sticky sole, in a bid to prevent slipping, as reported by The Sun.

Kate is a big fan of John Lewis underwear and hosiery, and you'll never catch her with a streaky fake tan leg!

The Duchess regularly wears tights to ensure her legs appear an even colour. It’s been reported she often opts for the Barely There Tights from John Lewis which has a non slip grip on the sole and anti-ladder technology.

Other clothes-related tricks include wear weighted fabrics to keep outfits from moving and Meghan Markle has been said to wear shoes that are too big for her, in a bid to escape blisters after a day in heels.

When Kate’s not strapping herself into her shapewear, she may also opt for the popular seamless underwear to avoid that visible panty line and lets not forget how comfy they are!

Myka Meier, a royal etiquette expert, once told The Sun: “Underwear and bras are considered private intimate wear, and for royals to put intimate apparel on display would simply not be done.”

So there you have it, It’s safe to say that after 18 years in the public eye, the Duchess of Cambridge has really got the knack of this royal dressing lark...
