When you can't decide what color would look best with your outfit, pull an Oscar. Grey is very easy to wear, so why not where it on your nails too? And with nail polishes like CND asphalt, the possibilities are endless. I'm sure most of you are familiar with OPI's "You Don't Know Jacques" (I own and adore it) which is especially great if you prefer a warmer grey to stone cold asphalt. Grey has many variants for example: a more purple grey would be "Metro Chic" from Sephora's OPI collection. Don't just settle for matte gray either, there are plenty of shimmers, taupes or colors with tints of grey.

Here is a list of other polishes you may want to consider:

"Particuliere" by Chanel

"Give me the moon" by OPI

"Sheer your toys" by OPI

"Over the taupe" by OPI

"Chinchilly" by Essie

"On the Prowl" by MAC
