Is any fashionista’s wardrobe truly complete without the Chanel classic bag? The Chanel classic flap bag is a treasured piece of fashion history and an iconic accessory cherished by stylish women worldwide. In February of 1955, Chanel released the 2.55 bag, the first shoulder bag considered socially acceptable for women of distinction and social status to wear. Since then, this bag has undergone many brand updates. Like the Boy Bag, the Chanel classic flap bag builds upon the beauty and sensibility of the original 2.55 bag.
