When it comes to vintage bags that never go out of style, the flap bag is definitely one of them! Next to the Baguette, the Flap Bag was an absolute hit in the 90s. The practical and spacious flap bag is said to have been first introduced by Coco Chanel, back in the 1950s. Her ‘quilted flap bags’ are still for sale and a sought-after collector’s item.
