Jessica Alba has proven her self a real denim aficionado over the years, constantly being spotted in the latest it jeans and denim trends. I am so curious what her denim collection looks like. Jessica works the double denim trend with her 7 for All Mankind Denim Jacket in Vintage Allston. She’s been spotted in this exact jacket more times than I can remember. That must be quite a compliment to 7 for All Mankind to see a denim connoisseur like Jessica Alba wear their jacket repeatedly.
