Uh? That's just an article about dresses trends, not even the Best Dressed list. Rihanna doesn't follow trends like others, she makes them. She's the headline of every relevant fashion site.
Her style permeates throughout all of culture. The GP has never endorsed couture but Rihanna makes it accessible to them. They respond by making cute and witty memes, while the high fashion publications foam at the mouth over the FASHION. She is the perfect must. Thats why she was made the face of DIOR and PUMA this year.
She's the face of so many high fashion and casual brands she's truly THE fashion ICON. I don't think Balmain, Dior, Puma, Armani, Gucci wanted a joke to represent them
She made the best dressed list and was the most talked about star of the night. Did it all while wearing an elegant Chinese-designed gown that actually followed the theme. She didn't have to show up nearly naked like a lot of the other stars for attention.
