A South Carolina native and former model, Carroll was a divorcée and mother of two when she wed her second husband, Milton Petrie, in 1978 (Carroll was wife No. 4 for Milton, who was 25 years her senior).

The less volatile, more low-key sibling, Bob Weinstein co-founded Miramax and The Weinstein Company with his brother Harvey. The Weinsteins founded Miramax in 1979, focusing on small art-house films throughout the '80s, including Errol Morris' The Thin Blue Line. The movie that ignited their careers—and the entire indie film movement—was Steven Soderbergh's sex, lies and videotape in 1989, which made Miramax the leading independent production studio in America. Bob and his brother went on a tear during the '90s, producing such films as Oscar-winners The English Patient, Shakespeare in Love, and Good Will Hunting. The brothers left Disney-acquired Miramax in 2005 to form their own production company. Bob is also the founder of genre-focused Dimension Films, now one of the Weinstein Company's most successful divisions thanks to franchises like Scream and Scary Movie. Bob found love in business: he is married to Annie Clayton, a former Miramax receptionist.

Weinstein is a legendary film producer who co-founded Miramax with his brother, Bob. Notoriously quick-tempered Harvey now presides over The Weinstein Company with his lower-key sibling. The Weinsteins founded Miramax in 1979, focusing on small art-house films throughout the '80s, including Errol Morris' The Thin Blue Line. The movie that ignited their careers—and the entire indie film movement—was Steven Soderbergh's sex, lies and videotape in 1989, which made Miramax the leading independent production studio in America. Harvey and his brother went on a tear during the '90s, producing such films as Oscar-winners The English Patient, Shakespeare in Love, and Good Will Hunting. In addition to an Oscar for producing Shakespeare in Love, Harvey has seven Tonys for his productions of numerous Broadway hits. The brothers left Disney-acquired Miramax in 2005 to form their own production company, producing a few semi-successful films (Hoodwinked and Michael Moore's Sicko, for example), though not approaching the success of Miramax in its heyday. His second—and current—wife is designer Georgina Chapman.

The precocious and exceedingly ambitious Posen has been a fashion star since the tender age of 21. The son of a painter (dad) and a mergers and acquisitions attorney (mom), Posen grew up in New York as an early-blossoming socialite amid a heady art and finance crowd. He attended the prestigious Saint Ann's School in Brooklyn, and, at 16, landed an internship with the legendary Richard Martin of the Met's Costume Institute. After attending Parsons for a while, Posen dropped out and enrolled at London's Central Saint Martins College, later abandoning the program to return to New York and start his label in 2001. While there's little question that Posen's enormously talented (a 2004 CFDA Swarovski-Perry Ellis award for emerging talent confirmed this), a good deal of his star status is due to his relentless networking skills, which hasn't always endeared him to critics. Regardless, his dresses make perpetual appearances on high-profile red carpets, worn by stars such as Natalie Portman, Anne Hathaway, Beyoncé, Angelina Jolie, and Naomi Campbell. While a student at NYU, Ashley Olsen was an intern at Posen's company. In 2008, Posen launched a collaboration with Target, bridging his celebrity designs to a new audience. Posen now lives in SoHo, his childhood neighborhood, with his boyfriend, stylist Christopher Niquet.

A timeless symbol of galas and awards shows and one of the few remaining members of the industry's old guard, Oscar de la Renta and his eponymous brand have long been associated with glamorous women of all stripes, from First Ladies Jackie Kennedy, Nancy Reagan, Hillary Clinton, and Laura Bush to younger style makers like Sarah Jessica Parker and Beyoncé. A native of the Dominican Republic, de la Renta got his start working for a number of international fashion houses—Balenciaga, Lanvin, and Elizabeth Arden, in Madrid, Paris, and New York, respectively. When he went off on his own in 1965, it didn't take him very long to make a splash. By the early '70s, he'd established himself as one of the preeminent couturiers in the country. In the late '90s, de la Renta's empire expanded when he licensed his name and introduced a line of accessories including bags, shoes, and belts. He stepped down as chief executive officer in 2004 and handed the reigns to his son-in-law, though he remains chairman of the company.
