In Paris for fashion week, Katie Holmes and Victoria Beckham are painting the town. . . black and white. As you can see in this gallery of their looks, these fast friends have a perfectly coordinated wardrobe that has us totally impressed. Look at how cleverly they play on proportions! For example, when Katie wears wide leg pants and a slim jacket, Victoria goes for a voluminous top and skinny pants — or a slim dress next to a full skirted gown– so they always look like interlocking puzzle pieces. And these two moms both share flawless makeup, killer pumps and the best oversized sunglasses on the continent. We were a little surprised when we first saw them hanging out, but hey, this is could be the beginning of a beautiful (and wildly stylish) friendship. Tell us: What do you think of Katie and Posh and their Paris debut? Will it last?
