According to Allure, the bestselling polish colors in each city reveal something about its residents. Kate Sullivan writes, "In Colorado and Montana, they keep things neutral with soft pinks, while New Yorkers prefer to make a statement with an edgy aqua."
In Austin, the bestselling polish is Sally Hansen Diamond Strength No Chip Nail Color in Coral Kisses. Popular in Bozeman, Mont. is Orly Nail Lacquer in Toast the Couple. In New York City, it's Sephora by OPI Nail Lacquer in Mermaid to Order; and in Edwards, Colo., Deborah Lippmann Nail Lacquer in Baby Love is the favorite.
