Dress of the Day: Gabrielle "Coco" Chanel, suit (ca. 1955). Staying with our theme of the suit I'm showing one of the most classic looks for women, Chanel's suit. In the 1920s, she designed several genre-defining pieces such as the tweed suit, the little black dress, and other sportswear separates such as cardigans. Over the decades, Chanel herself and then her house designed tweed suits in many colors but often with elements you see here - contrasting trim, boxy jacket, and accessorized with strands of pearls.
