I don't buy crazy expensive brushes like many people do, i think theres some great cheaper alternatives out there and the shape is the most important thing...not the brand thats plastered all over it. These two brushes :- big fat one i use as an all over face blusher/bronzer brush. The smaller brush i use for more precise blusher application.
My eye brushes, (top to bottom) brow brush for getting that foundation out my eyebrows!, big flat brush used for all over wash eyeshadow application, the 2 slanted brushes i use for lower lash line work and the bottom one as a more precise eyeshadow colour brush with either powder or cream shadows.
These two I've literally had for about 6 years both by Ruby and Millie, i got them in a gift set years ago. The top brush is my favourite eyeshadow brush for both lid application and blending. I use the smaller slanted one to line the inner corners of my eyes with a very light cream colour for that wide fresh eyed look.
Anybody else have any brushes they cant live without?x
