MAC 217 - This brush is my go to. It's perfect for both applying eye shadow to the lid and blending. It's lovely and fluffy - creating a soft look.

Body Shop Eye Shadow Blender Brush - This brush is seriously old, but a great part of my collection. I like to use this is blend colour into my crease.

MAC 209 - This brush is great for adding tiny details. I like to use this to apply almost an eye-liner-like line of colour to the eye, close to my lash line.

Real Techniques Detailer Brush
 - This brush is the one I use most under the bottom lash line to create a smokier eye look and add even more colour.
