If you're tapping your nails on the conference room table during the most boring meeting of your life, you don't want your tips to speak louder than your words. Office-appropriate nail polish can range from neutrals with just a hint of color to deeper hues that are timeless classics. Consider the dress code at your office when deciding how bold to go with your nails.
A natural palette in shades of buff, grey, beige and barely-there pinks and peaches works well for a conservative office. A soft pink can also carry you easily through a workweek of outfits as it coordinates with almost anything. Both cream and frost finishes can be pulled off in shades from icy pearl to a muted dusty rose.
Bold Yet Professional
If you want to go a bit bolder in the boardroom, stick with the classics. A traditional apple-red polish works well and becomes even more sophisticated if you go a few shades darker -- think rich burgundy or garnet. A cool shade of gunmetal or a deep bronze can function as a workplace-appropriate metallic. To go dark without black tips, which is best avoided, try a conservative deep navy cream.
Unless you're working in an especially freewheeling, creative office, it's best to save chunky glitter or topcoats with funky effects for the weekend. This doesn't mean you can only wear a cream finish -- a delicate shimmer in the polish is acceptable, particularly in lighter hues. Avoid bright neon shades or any nail art that pulls attention to your nails and away from you.
