Hola Munchkins!
Lately, I have been noticing myself reaching for the same brushes day in, day out, and seeing as they seem to work for me, I thought I'd share them with you =).
So, starting from Left to Right:
Prestige Brush  - used for contouring and highlighting, this is the perfect medium size for a defined, but soft contour that is perfect for everyday use.
Crown brush - an angled brush that I use mostly for my cream blush. It stipples the cream blush on in a natural way that can easily be built up for a more dramatic, or doll-like look. 
Bobbi Brown Cream Eyeshadow Brush - perfect for a base like my Mac Paint Pots, or for packing on colour, especially a shimmer or glitter-based eyeshadow.
Crown Brush - the absolute perfect blending brush. Wonderful for sweeping on a wash of colour, or blending out any colour, especially for a smoky eye.
Sigma F82 - the most perfect foundation brush ever.  Buffs, stipples, and makes your foundation look absolutely flawless.  
Cosmopolitan Beauty Blender - a rediscovery and absolute new obsession. Makes all foundations, even the thinnest and lightest formulas, look absolutely flawless. Works best when spritzed with water or toner first.
And that is my everyday brush kit.
