Make up looks terrible when its overcast outside?

Do your make-up by a window with plenty of natural light, that way you get a clear representation of what you will look like with your make-up on. It'll help you apply the right amount. You could do this everyday as well to apply your make-up to perfection. Alternatively you could wear no make-up until you go out somewhere and then when you do everyone will be like "wooowww" you look great.
