And it's seriously cheap too.

After a fairly hectic 16-day royal tour of Australia, Fiji, Tonga and New Zealand, we’re guessing Meghan Markle is feeling fairly knackered at this stage. Not to mention the fact that she’s expecting her first child – it’s tiring work. But there’s one little trick the Duchess has incorporated into her beauty routine to keep herself looking fresh and it’s seriously simple. According to celebrity makeup artist, Francesca Abrahamovitch, Meghan has been embracing a new makeup product to help disguise the tiredness.

“Meghan appears to be wearing a nude eyeliner in her lower waterline,” Abrahamovitch told DailyMail. “I love this look and use it a lot on my clients, especially when they have super-early starts.”

Yep, it’s as simple as a lick of eyeliner and there are some seriously great budget options available so you can achieve the same look yourself. One of our favourites is the old classic from Rimmel, the Scandaleyes Waterproof Khol Kajal Eyeliner in Nude. But we're also big fans of the NYX Wonder Pencil and the Kick-Ass Blur and Brighten Crayon from Soap & Glory.
