Very rarely do we retrogress back to the ’40s to derive beauty inspiration, but if ever there was a wartime look to repeat, rockabilly victory rolls absolutely gets our vote.

Made famous by voluptuous sex kittens of yesteryear, it’s no wonder modern-day pinup Katy Perry is at the forefront of this revival—also seen on the Fall 2011 Miu Miu catwalk.

Thing is, there’s good news and bad news about this one. The bad news? This architectural-esque look is anything but DIY for beginners, though the brave can follow this excellent step-by-step tutorial. The good news? As Madonna and Diane Kruger prove, it is simple to simulate.

While the ‘material girl’ leaves hair loose on both sides for a breezy bohemian style, and the German actress’s locks are neatly brushed for a more polished look, both versions are quick and easy to recreate—and a great way to reinvent curls that are a few days old.

Starting with soft messy waves, insert a short off-center part using your forefinger. With both hands, roll a large section of hair away from your face, securing mid-crown with a few small hair pins (we love Conair Styling Essentials Mini Pins, $6.99 at Amazon.com).

For a bit of volume in the front (like Madonna’s look), gently insert your fingertips into the roll and loosen and lift strands by wiggling your digits. For a cleaner look, à la Diane, brush the hair above both ears back and pin alongside the roll. —India-Jewel Jackson
