Grey or Black is a scary look to create as it can turn into a mess real quick. However here is the perfect grey look that is really easy to do.
First with a really light coloured eyeshadow you want to apply this allover the lid up into the brow.
With a large fluffy brush and a light grey brown shade apply this to the crease and lower lash line.
With a slightly darker shade of brown you want to do the same thing keeping it a little lower than the last shade. This will help to keep it blended.
With a dark cool toned brown you want to do the same thing again. Once again keeping it lower again.
Going back in with the very light colour and a flat brush you want to apply this to the lid again and brighten this up as you would have lost this colour a little after blending the other colours.
With a black crayon you want to apply this to the waterline and blend this out a little on the lower lash line.
To finish off the eyes you want to apply mascara to the top and bottom lashes and then apply some false lashes.
To darken this look up a little add a tiny amount of black to the outer part of the eye. Make sure you apply a little bit at a time and build until you are happy with the look.
For this look I paired this with a cool toned brown nude lip and light pink to the centre of the lip.
