J.Crew’s Jenna Lyons has been on a publicity spree as of late. She peered behind her trademark eyeglasses on the latest Fast Company cover, made up words while discussing her juice cleanse, and even let the magazine take a 360-degree panorama of her office. And in just a few weeks, she’ll be in the spotlight again — this time, using her brand’s influence to share it with the 2012 CFDA/Vogue Fashion Fund winner Greg Chait of The Elder Statesman, shoe designer Tabitha Simmons, and jewelry designer Jennifer Meyer, who have designed limited-edition capsule collections for J.Crew that will be available online May 22. For those itching to get their hands on these collections earlier, there’s semi-good news. You can get access just one day sooner by signing up online on May 8.
