The 272 is my all time, hands down, favorite eye brush. It is fluffy, it can be fat, or thin, and it picks up a decent amount of product. I often do my entire eye (sans lining) with it.
190-for foundation
217-Blending especially for the crease-love it!And for basic eyeshadow application too
239-i love it because you can pack plenty of color on it and I use it to line the inner lower and outer lower lash line with eyeshadows
187 for applying Studio Fix foundation/Blot Powder
219 for applying eyeshadow to the lid and crease, and to apply Studio Fix when touching up small areas
217 to blend eyeshadow
