I wear Laura Mercier - oil free - $90 for 50 ml and worth every penny!

I always get comments on my skin when i wear this (which is not that often) and its the only foundation i've ever tried which i put on and actually makes my skin look fantastic but like i'm not wearing anything. I dust a light covering of translucent powder over the top and thats it.

The price isn't bad too when a bottle like that would last me a year, and that is based on wearing it twice a week or so.
