Project Makeover

Since the hit reality series Project Runway premiered on Bravo in 2004, Tim Gunn has delighted millions as mentor to the show's dueling designers. Although he's best known for his compassionate criticism and signature catchphrases, Tim is no stranger to the industry. He's been working in fashion for more than 20 years.

When the cameras are off, Tim serves as fashion chair at Parsons The New School for Design in New York City. He visits The Oprah Show to share the six things that no woman over 40 should ever wear.

Although it's not a long list, Tim says it's an important one. Women in their 40s should always try to avoid horizontal stripes, jackets that hit at mid-thigh, pleated pants, double-breasted blazers, Capri-length pants and low-rise jeans.
