Everything old is new again, and that's certainly true of two boutiques that cater to those who love fashion that not only has a pedigree, but is the ultimate in sustainability. Two new series focusing on well-known purveyors of vintage fashion premiere this week: Bravo's "Dukes of Melrose," debuting March 6, and Smithsonian Channel's "L.A. Frock Stars," launching March 7.

"Dukes" follows Christos Garkinos and Cameron Silver, owners of the vintage boutique Decades, who are introduced in the opener as they prepare to dress celebs for the Oscars. "Frock Stars" focuses on Doris Raymond (pictured right) and her store, The Way We Wore. She sells fashions from designers like Chanel, Versace, Dior and Halston to such celebs as Dita von Teese, seen in the first episode, and Debi Mazar, seen in the fifth. The series will also show how Raymond, who has supplied wardrobe for major film and television productions — including "Titanic," "Boardwalk Empire" and "Glee" — procures her rare pieces at auctions, estate sales and from private clients, and competes to dress stars for awards season.
