1.) Colored Jeans
A splash of color doesn't come quite as extravagant as colored jeans. You could be wearing black or gray everything else and bright jeans would brighten up the entire outfit.
2.) Adding a Colored Accessory
When it comes to Winter accessories, scarves are ideal. Add a colored scarf, hat, or pair of gloves to brighten up and add a glow to your outfit.
3.) Colored Boots
Unfortunately, Winter is cold. Therefore, you should be prepared and wear boots. But most boots seem to be dull and colorless. Add a colored pair of boots to any outfit and the attention will be instantly drawn to your feet.
With tights, you can wear skirts or even shorts in the Winter and not absolutely freeze your butt off. But if you wear colored tights with a mostly black or gray outfit, the entire outfit becomes bright.
This is for the girl who doesn't want to add a lot of color to her outfit. Adding a colored belt will add just that subtle splash of color to make your outfit not entirely boring.
