Use shadowing down the sides of your nose and lighter foundation down the front of your nose.

Slim down a broad nose with a foundation that is one shade darker than your natural skintone. Sweep along the sides of the nose with a small, firm makeup brush. Start just below the inner corners of the eyebrows, and end at the sides of the nostrils.

Stroke a lighter shade of foundation down the bridge of the nose. Blend well.

use a bronzer to contour yourr nose but putting it on the sides and then putting a highlight on the bridge of your nose!!

foundation and use a bright lipstick or something to keep attention on instead of the nose. it helps, i don't have a bulbouse nose though.

I would use bronzer to contour the nose! just work a little on the sides and to the desire shape. Use a small blending brush to work the bronzer into the skin to give a natural finish.
