Oscar de la Renta is still learning about fashion.

The 77-year-old designer - who counts Megan Fox, Sarah Jessica Parker and Cameron Diaz among his fans - says he is fascinated by the industry and won’t quit until he knows everything there is to know:

“People always ask me how much longer I am going to do this, and I say the day I learn everything is when I should stop. I am a curious person, so every day is a learning process. There has never been a time as challenging as now to create clothes.”

Oscar admits he has to work hard to maintain his customer base because women nowadays have so many more designers they can choose from.

“Back in the 60s, my customers only got their clothes from one place. Today, that loyalty doesn’t exist as women want to project their own individuality through fashion. It’s about understanding the needs and aspirations of professional women that makes it so exciting.”

Yesterday, Oscar received the Colleagues Champion of Children Award at the charity’s annual spring luncheon in Los Angeles.
