"As far as my nails, I like being dramatic onstage and having fun and doing something that I might not do in my everyday life. It's all about playing a character. I would definitely throw on my shade, my signature shade, for something a little darker," Underwood said.

Underwood worked with OPI & Nicole by OPI Executive VP & Artistic Director, Suzi Weiss-Fischmann, to develop the 14 new nail lacquers. The collection features a colorful mosaic of hues ranging from soft pastels to dark sultry shades to playful glitters as well as the country singer's signature shade: a gold textured lacquer called Carrie'd Away.
