So what happened to the extra flared pants that didn't get snatched up in the rush when today's thirty- and fortysomethings were in high school? More than likely, they're on the racks at Plush Living, labeled "new old stock" because they still have the original tags on them. Plush specializes in Disco, Pimp, Hooker and all that is '70s Baaaad, though occasionally some great '50s and '60s threads turn up here, too. We find it hard to concentrate on shopping, because we really like chatting nonstop with Curtis Gannon and Amy Bowling, the shop's hip proprietors. But we tear ourselves away to check out the upstairs for fetchin' furniture, with the emphasis on Brady Bunch Mod and I Love Lucite. Austin Powers fans will be happy here, as will anyone with a hankering for his old high school wardrobe.
