Practically every fashion-forward star, not to mention Kate Middleton and the Obama sisters, has tried out the colored denim trend, but Jessica Alba really, really loves the look.

The mom-of-two, 30, owns jeans in almost every color of the rainbow, wearing the eye-catching bottoms with everything from patterned tops to sleek blazers.
