To really have the perfect appearance, nail art can be the right thing for you to put effort on it. In this case, since the season is winter, then you can apply the winter theme into your nails. For your example, you can have the snowflake pattern, glitter for the snow falling accent, or certain pattern that can represent the season.
For long nails, this kind of nail art brings glamorous touch. On the other hands, for short nails, it gives artsy and classic look.
