Top tip: "The eyeliner flick should go up to where your brows end so do your brows first so you can map out your flicks and make sure they are even! I prefer to use gel liner because it gives you a matte finish."

Step 1:

"I always start by applying my liner in the centre of the upper eyelid - I just find it easier to see what I'm doing that way. So, starting in the centre, draw a line each way along the top lash line, as close to the lashes as possible.

Top tip: Try and keep your eyes open when doing liner so you can hug the liner to the lashes - without having an awkward gap between your liner and lash line."

Step 2:

"From the outside corner of your eye, draw a line angled upwards, approximately 1/8 inch in length, towards the end of your brow."

Step 3:

"From the tip of this line, draw back towards the lash line about a third of the way along the eye."

Step 4:

"Fill in the gap and apply mascara."

Finishing touch:

"I like to complete classic liner with a red lip stain."
