1. After applying your typical complexion makeup (moisturizer, concealer, foundation, etc), swirl the tip of your flat eyeshadow brush into your bronzer or contouring powder. Starting at the upper side of the bridge of your nose (under the head of your eyebrow), lightly trace a line going all the way down to the nostril. Repeat on the other side of your nose.
2. After you have drawn the lines on both sides of the nose, draw a line horizontally from one nostril through the tip of your nose, to the other nostril.
3. Using your blending brush, blend along the bronzer/contour lines you drew to "fade" them into your skin.
And there you have it, a slimmer nose in no time! Below you can compare the difference this makes. I am sorry that I do not have photos from the same day, but you get the point:)
