Fair skin looks best in colors that don't overpower it. Cool pale skin suits soft blues, lavender, rose and navy; warm pale skin suits peach, coral, mint and camel. Very dark, heavy colors can drain it unless your hair is dark too.

Navy or charcoal instead of black if black feels harsh.
Soft white or ivory beats stark white.
If your hair is dark, you can handle more contrast.
