Love Metro chic by Sephora by OPI. It's a mixture of gray/purple making it one of those fun dirty colors. Sephora describes it as opaque dark smoke with a hint of purple. It's such a unique color and one that I get the most compliments on. This is a holy grail product for me, and one that I'll repurchase as long as Sephora/Opi do it. It's perfect for fall. If I had to pick the perfect fall/winter color and one I would purchase over and over again, this would be it.
What is your favourite dirty/dark polish for fall and winter?
