My favorite colored pants: Cobalt!
Cobalt can be considered a new neutral. It pairs well with reds, purples, yellows, greys....and the list goes on. Consider adding cobalt blue to your wardrobe for an extra punch in everyday looks.
With cobalt pants, why not go crazy? Add a nice patterned scarf or blouse and patterned shoes. With cobalt as a neutral, the mix of pieces will play nicely.
Scarf: Germany (!)
Shoes: Urban Outfitters
Hope you had a wonderful holiday!
