i've heard erase paste is good but i use laura mercier's secret camouflage in sc1.
Don't know about eyeshadows but i love Nars and Bobbi Brown for eyeshadows, Bobbi for her matte's and NARS for their shimmers, also bobbi for liquid pot eyeliner simply because of the massive choice of colours and the quality of the powders. Everyone loves MAC and yes i have been able to buy things from there, like Naked Lunch which is lovely eyeshadow but their colours tend to be too garish for my tastes, but it is a matter of taste
i swear by MAC's Naked Lunch, Bobbi's Taupe and NARS Kuala Lumpur, All about Eve and Earth Angel duo eyeshadows. just a few recommendations
I only started doing makeup recently and i've been studying hard lol, finding all my favourite products, but everyone is different.
