Bring in your old jeans to Barneys and get 20% off your next pair. I don’t see my favorites, Acne, on the list of brands participating. But I do see Goldsign, which had an eye-popping pair of spray-painted silver jeans on display recently. Very glam rock! I’m sure Marc Bolan would have dared to wear them. The Barneys offer begins today and runs through August 19. Also, check out J’Adore Vogue for info on hot jean styles and Zafu.com for help with fit.
