My favorite nail polish this summer was this soft lavender, and I still love it but I felt the need to change up the mood with the colder weather. This butter London nail-polish is the perfect color for colder days; it’s my go-to color in the fall and winter. I think nail polish can really add to the overall look; and I for one really notice it. This color is sexy yet the rich mixture of what seems like part brown, part purple makes it deep and sophisticated as well. What is your go-to color for colder days?
