During the winter there are certain shades that you have to pull out to wear on your nails. I have been rotating classics like Chanel's Lotus Rouge, the perfect winter red with a new classic of dark brown like Essie's Little Brown Dress. Little Brown Dress has been my new staple that has replaced black in my polish this winter as a great dark neutral tone.
You can wear glitter polish during every season and Deborah Lippmann is the best glitter polish for sophistication. Her gold, Boom Boom Pow has large glitter that I have loved since I purchased here. My newest favorite was a find in my stocking, Butter London's Mariner. A deep midnight blue that is almost pitch black but shines off the blue hue.
