I love navy blue. It's one of my absolute favorite colors, and it was our main wedding color (with accents of silver and shades of purple). Since I started loving dark polishes, I've been dying to try a navy shade, and I found the perfect navy blue in Essie's Bobbing For Baubles.
The accent nail is Color Club's Diamond Drops polish. I can't seem to stay away from glitter. Plus it's great for winter. I have no idea why, but it is.
