Powder bronzer ?

oh my!

don't put it all over your face.

well

you can get a bronzer brush (big, contoured fluffy soft brush)

and highlight/contour your cheeks (mostly on the apples of your cheeks- make a fish face by sucking in your cheeks and apply on the cheekbones!)

that's for a more subtle look

but if it's evening and you're going out ;)

then put the bronzer on the cheeks, a very light brush on your forehead (so its barely noticeable), a light brush on your chin, and a light brush on your nose. this contours your face very nicely, and looks natural in the sun! =]

have fun ^^

only places you want to high light like your cheeks. dont put it all over because then you might just look like you went to the tanning beds a little too much!

on the parts where the sun hits your face only and do it lightly so it doesnt look cheep !
