Mary-Kate and Ashley. I love them both and especially their clothing line The Row. It launched in 2007 and is still expanding into more items today. It's very classic looking and perfect for any career. A lot of their pieces are very basic, but there is something unique about each one. It's a very solid collection, all in the same color range and style. It's sophisticated and clean cut, most definitely a luxury line. The two twins are such an inspiration when it comes to clothes. I personally love Ashley's a little bit more, it's more conservative while Mary-Kate's is very bohemian. The other picture is Brigitte Bardot! They're holding up her book in the first picture. She's a french model and actress who is also very iconic! Just had to include her pic:)
You can find The Row at Bergdorf Goodman and Barneys.
