For the last few weeks I've been finding myself reaching over and over for the same blush color: Shu's Glow On in M Amber 82 (in that small box to the right). It's actual a bit more neutral than the image shows. This is a light peach/rose with some nude thrown in.
I've been applying it with my MAC 116 Blush Brush, which is a small-medium rounded brush. It fits perfectly on to the blush palette, fits the apple of my cheek just right and applies just the right amount of blush.
