Here is an example of the up-and-coming trend of colored denim. I have seen brightly colored denim in hues such as red, cobalt blue, and kelly green in a couple of stores. The girl pictured above represents the first person I have seen pulling off this trend this season. I like how her outfit is not matched.
I remember when colors such as these were popular for denim back in the early 1990s. Here's a great 1990s flashback - remember Cross Colors?
