Looks fantastic!! (As always!)
One would think that the opposite would be true, that your body would be lighter than your face for the fact that you wear clothes, but the sun gets right through clothes and the only thing I can think of is that your foundation has some sort of sunscreen in it :x
I know this because the sun makes me very ill, and one day I was sitting on the beach watching my daughter swim with a long sleeve shirt on, and my whole back and arms got sunburned really bad...through my shirt. :\
