Mascara: No matter what your hair color, use black mascara. It will define your eyes and make you appear more wide awake.
Foundation: A full face of foundation can feel heavy, so instead of applying it all over, touch up only those areas where your skin tone appears uneven.
Concealer: Choose a concealer that is long wearing or gives medium to full coverage in a shade that's close to your skin tone.
Blush: To choose the right color for a subtle look, find a shade that's similar to the inside of your lip.
Eye Shadow: A neutral shade acts as a base and will instantly brighten eyes. Use one with a bit of sparkle for a more festive look.
Lipstick: Try a moisture-rich formula so your lips don't dry out. (The inner-lip trick for choosing blush works for lipstick shades, too.)
Brushes: One or two all-purpose brushes, like the medium-size dome brush here, will help. But in most cases a cotton swab (or a finger) will do.
