Christie Brinkley thinks "ageing is the last frontier" for the modelling industry. The 67-year-old model thinks the business has evolved markedly over recent decades, but she still thinks ageism remains a problem. She explained: "Women tell me that they want to see themselves in there. They want to be stylish but they donât want to look like theyâre trying too hard. They want to be represented. "Iâve been in this industry for 47 years now and I canât begin to tell you how much it has evolved, but ageing is the last frontier." Despite ongoing issues, Christie remains in love with her job and is desperate to keep working.
