The first full issue of Carine Roitfeld's biannual magazine, CR Fashion Book, won't come out until September. But she just couldn't wait that long, so she's releasing its first installment, "Issue 0," as an insert in the next V magazine, "The Youthquake Issue," on newsstands July 5. (CR is published by the same company as V, Fashion Media Group LLC, making for a cozy, siblinglike relationship between the two magazines.) Here's a behind-the-scenes video of Roitfeld working with photographer Sebastian Faena on a pre-fall fashion editorial that will appear in "Issue 0." Apparently we can look forward to lots of mirrored floors, Frida Aasen, and multiple wig changes.
