Ah, the infamous MAC 217. Probably the most hyped up brush in the blogging world, and a rightly deserved one at that. This is the brush that got me into eyeshadow as it just made the application so darn easy. It's one of those 'do it all' brushes, from color placing to crease defining, and of course, blending, you can get your eyeshadow look done with this one brush. However at £18, it's not the most affordable brush and while I do want multiples of this, I'm not willingly able to part with that chunk of cash for it.
