If you don't want to play with colors when doing your nails, then play with the design by sticking to black. Black nails are among the most interesting, they show character, class and sometimes even courage. If you're not into girls wearing red nails in December, here are some ideas for December and all the winter months :)

1. Ombré with black highlights

2. Matte + Gloss

3. Mod-Block French

4. Spikes & Studs

5. Charmed French
