Bobbi Brown Fawn is my all time fave eye-shadow. I have green eyes & the purple undertones work really well with my eyes.
I usually use a Mac paint as a base & add fawn to my lids & crease, bringing a little of my pink blush up into the crease as well.
This has never failed me, it always looks fantastic & i can build this product to a really nice smokey eye.
It lasts forever.
