If customers ever want to know which nail polish colors compliment their skin tones, InStyle's November 2011 article "Best of the Web" recommends pointing them in OPI's direction!
On the company's website, clients can click on the "Try On This Color" tab to receive virtual manicures in any of OPI's 250 polish colors.
The interactive site allows visitors to adjust skin tone and nail length on a virtual hand for accurate results.
The same article also recommends searching on Amazon.com/beauty for hard-to-find salon must-haves, like a discontinued Essie polish. Amazon has a large selection and an easy ordering process.
