Looks very natural
I initially bought this for a client who was getting married and had been tanning. We picked Shade 4 for her and I loved the way her skin looked afterwards: very dewy and natural. I bought Shades 8 and 8.5 for myself as I am darker/lighter in some areas of my face.
I am a fan of M.A.C. and think they hit the ball out of the park with this foundation, as it is lightweight yet truly build-able for more coverage. It's easy to manipulate and as a dry skinned person, I didn't have any problems with oil control. I used Smashbox Photo Finish Primer underneath and I used M.A.C. Studio Careblend Pressed Powder to set my foundation.
