if you really want to look dewy, you will need a bronzer IMO. Forget foundation.
Also, mix bronzer with a nice lotion and then go back over it without lotion on just your cheeks and eyes. you don't want to look like Eva Pigford with too much everywhere.
I use
Makeup forever liquid bronzer
low-shine glitter ( extra fine) bronze powder... this type of glitter is more mineral and less go-go girl.. when you brush it on it looks lik eyour skin is wet.. the one I use is a random mineral one it is more refined than typical glitters.
Nice dewy look (via Bronzer)
Too much...
