What's the best way to recover from a political convention? Shopping, of course. Fresh from a raucous standing ovation at the Republican National Convention in St. Paul, first lady Laura Bush hit Georgetown's John Rosselli & Associates, a chic purveyor of antiques and furnishings. "She likes to come in and look at everything that's new," says Matthew Esposito, an associate at the store. Bush and sister-in-law Margaret checked out some fancy chairs upholstered in teal fabric by le gracieux but left empty-handed. Turns out she's a regular, recently helping daughter Jenna and son-in-law Henry Hager furnish their home in Baltimore. "She's lovely," Esposito says of Laura. "We love having her here."
