Katie Holmes has been making quite the stylish exit from her NYC apartment these days. First she showed us how to make gingham cool, then she paired denim on denim with camel, and now she's giving us yet another combo to love: heather gray with light blue denim. Notice how Katie's heather gray blazer gave subtle polish to her light blue wide-leg jeans, and how the jeans lent '70s cool to the blazer. You can mimic her exact look, or this combo need not be reserved solely for blazers and wide-leg jeans; you can do a heather gray sweater with skinny jeans, or a zip-up hoodie with boyfriend denim, and so on.
