Proenza Schouler‘s Spring 2010 collection, with its covetable tie-dye separates that ooze surfer girl cool, is now just a weekend craft project away! On the The Martha Stewart Show yesterday, designers Lazaro Hernandez and Jack McCollough showed viewers how to DIY a brightly-patterned tie-die scarf. Forget rubber bands and buckets of harsh chemicals: They created multi-colored silks using Simply Spray fabric paint. Still, perfection is all relative: “Mine is terrible, Martha!” laughed McCollough when he showed his final product to the domestic goddess. Pressed for time or just got a manicure? Proenza Schouler’s tie-dye tank—sure to be your summer go-to—is now available for a limited time only at proenzaschouler.com. Check out the boys’ how-to video after the jump!
