Here is a list of the ten females I feel have made the greatest impact on style over the years (in no particular order):
1) Grace Kelly: Her look was timeless and classy. Who did not want to look like this Princess? Born to a well-to-do family she was a model and an actress before becoming Princess Grace of Monaco. The lady epitomized style and poise. Her wedding dress is iconic and now is a museum piece.
2) Audrey Hepburn: She also possessed a timeless look that has been copied over and over. She was the queen of knowing her body and what worked for it. Knowing that just a belt or a scarf could change the whole look of an outfit, Audrey Hepburn had a very collaborative relationship with all her stylists. She had a longtime relationship with designer Givenchy.
3) Madonna: Everything this woman does becomes popular and influences people. In the 80s she had everyone dressing in ripped clothing, sporting tons of black rubber bracelets and showing their midriffs. She changes her looks as often as others change their underwear. Through her career she has gone from Goth to S&M wear to Western.
4) Gabrielle 'Coco' Chanel: She may be the original style icon. For her fashion was everything and the most important thing. She made Chanel what it is today. A woman who is probably on everyone's Best Dressed list.
5) Jackie Kennedy Onassis: During the 1960s her jackets, hats, how she wore her hair, and her general appearance were copied by women all over the world. Even today those Jackie O sunglasses and clothes are still worn. She was an original. Her appeal has been enduring.
6) Sarah Jessica Parker: A newcomer, but worthy of being on the list. Ever since "Sex and the City" and its emphasis on fashion, SJP has become who women today look for style. Taking chances that usually work out and being shoe obsessed have become Sarah Jessica Parker's trademarks.
7) Katherine Hepburn: Her embracing of pants for women broke all kinds of boundaries. Now it has become commonplace. She made it 'all right' for women to wear casual, comfortable clothing that you could move about in.
8) Princess Diana: Despite her brief life, Princess Diana became one of the biggest fashion icons of her time. During the 1980s her confidence grew and her fashion sense followed along. She truly understood what suited her and was very elegant in her choices. Stores began to copy whatever she wore – a true sign of your fashion impact.
9) Anna Wintour: The British born Editor in Chief of Vogue magazine who Meryl Streep's character in "The Devil Wears Prada" was based on. What this woman likes, fashionwise, goes. She has made and broken the careers of many fashion designers.
10) Diane Von Furstenberg: This female designer created the wrap dress. During the 1970s she became fashion's "it" girl as she ran around New York with Bianca Jagger and the like. Through ups and downs this dress has always stayed in style.
