If you’re in the New York area this weekend, you can help make a difference — while grabbing a little something for yourself, too. On Friday at 3 p.m., Roxy and Clothes4Souls are kicking off their winter clothing drive at the Roxy Times Square store. Simply donate a gently worn piece of clothing, and receive 40 percent off of your denim purchase. Snowboarder Torah Bright will be on hand to offer style tips, and customers will be invited to decorate their new denim at a craft-filled DIY table. If you can’t make it Friday, not to worry; Roxy will be collecting clothing and offering discounts at all of its New York locations — including SoHo and Fifth Avenue — through Dec. 23. Happy holidays indeed.
