The talented chap took to Instagram yesterday (29 March) to share his secret to perfecting a winged eyeliner – take note, girls!
In the snap, Kim looked incredible as always with slicked back glossy locks that showcased her incredible make-up.
As well as sporting her favourite contoured cheeks and flawless skin, the reality star had beautiful, bold brows and a pretty shimmery gold hue on her peepers. Stunning!
But of course, what really grabbed our attention was the perfect flick that had been drawn across Kim's eyes. Winged eyeliner is a classic beauty look that's super flattering and will go with pretty much any lippy choice.
However, it can sometimes be pretty tricky to make sure your flicks are even and precise. So we were thrilled to see Mario reveal his advice on getting it just right.
Captioning the snap, he wrote: "For a classic winged eyeliner look, try using a pencil or cream liner first to perfect your line, then follow with a liquid liner to intensify."
Sounds good, right? By doing this, you can really take your time to get your peepers exactly how you want them and will be able to easily remove it if you make a mishap.
Make just like Mario and pick up a pencil number – we love the penny-saving Rimmel Soft Khol Kajal Eye Pencil (£2.99).
Then faintly draw out your desired shape. Trace along your upper lash line with a steady hand – it's best to start off with a thin line and then you can add to the thickness when you're happy with the initial shape.
For that all-important wined finish, put a dot where you want the flick to end, then simply draw down to the outer corner of your eye, joining up the line!
Copying Mario's tip, you can then get your flicks super bold with liquid liner. He revealed that he's a fan of MAC Liner (£15.50).
We also love Max Factor Xpert Liner (£6.99), which is super easy to use and completely budge-proof.
