Choose bold, vibrant primary colors of clothing. Go for bluish reds, instead of those with orange bases. Choose royal blue over other blue tones, and select greens with a blue base. Black and white also work very well with your coloring.
Also choose icy pastels, which will really flatter your natural coloring.
Avoid clothing in yellows, oranges, rusts and all but the darkest of browns, as those colors can make you look tired out. Avoid dusty shades too (desert rose, beige, etc).
