Carolina Herrera's wardrobe staple is a white blouse.
The designer is famous for her beautiful gowns which have been worn by a host of celebrities including Renée Zellweger, Amy Adams and Tina Fey and also designed the wedding dress for the 'Twilight Saga's Bella Swan but Caroline takes a more laid back approach to clothes herself.
She explained to aarp.org: ''I love them and I've worn them all my life. They are my security blanket, as they say. They make me feel secure, and I can match them up with anything. They're very feminine, and when I'm getting dressed in the morning and can't decide what to wear, a white blouse always fits the bill. They also bring back happy memories. As a child, I wore white blouses to school, and I remember them always being ready and perfectly ironed.
''They go better than anything else with certain outfits, short skirts as well as pants, and even long evening skirts. They're also very flattering, because they light up one's face.''
However, Caroline, 73, doesn't believe style comes from the clothes people wear but rather how they are worn.
She added: ''True style money can't buy. Style is something subtle that shows in small details. Clothes have to look neat, well-ironed, buttons in perfect condition. I'm always saying that about clothes. What good does it do you to wear an expensive dress if one of the buttons is falling off or if it hasn't been properly ironed? Or to wear really expensive shoes if they're dusty and scuffed?''
