Cherry
I cannot tell if it is a habit or some deeper need, but I wear something red every summer.
I like red a lot, actually, but I think it looks best in good light, combined with light neutrals and a good tan.
Red is the color of power and passion and looking at red actually raises the metabolic rate and the heart rate. Red is also warm and sensual, and brings a nice edge to my otherwise plain summer wardrobe.
