Play by C. Ronson for Urban Outfitters

A thoughtful, well-executed collaboration is a thing of beauty-just think how much lovelier life is in a world with Bottle Rocket (Anderson and Wilson), Mozza (Batali and Silverton), and She & Him (Deschanel and Ward). Since we truly believe in the power of partnership, we did a little dance o' joy when we heard that Charlotte Ronson was working with Urban Outfitters to create PLAY by C. Ronson, a mini-line available exclusively in UO stores.

The PLAY by C. Ronson collection is very appropriately named, as each piece seems to have been cut from the same sweetly frolicsome cloth-figuratively speaking, of course. Where Ronson's eponymous line is more polished, PLAY by C. Ronson has youthful energy in spades. For example, the UO collection includes reversible tanks and rompers (stripes on one side, polka dots on the other, how fun is that?) and other soon-to-be favourites like snuggly cardigans in grey or green, flattering day dresses, and an excellent cuffed pair of railroad stripe shorts.

The designer herself has a soft spot for the Rosebud Blouse, as Ronson's particularly keen on its unfussy print and perfectly worn-in fabric. "It's like my old favourite t-shirts," she says. "The cotton is very soft and it feels like vintage." We asked her how she'll personally style the blouse and her answer hit our fashion bull's-eye: "tucked into any piece of denim from the Current/Elliott collection," (she's as obsessed with the jeans as we are!) and a pair of Manolo Blahnik for Thakoon high heels.

While we approve of that outfit, the blouse, like the rest of the collection, is highly versatile and really could go with so many things in any wardrobe. For this reason alone (not to mention the limited availability and excellent price points) we have a hunch that PLAY by C. Ronson is going to sell out quickly, so check out the collaboration before it's gone!
