While the Boy Bag won't ever replace the popularity of the 2.55, it's the only bag that has come close to the timeless classic. With a more modern and boxy shape, this chain-strap bag takes some cues from its older counterpart, while adding a little edgier and more youthful vibe. Since debuting in 2010, it has remained a mainstay in each season's collection, designed in countless prints, colours, textures, and more to date. Fun fact? Karl Lagerfeld named the bag after Coco's first love, Arthur Capel, whom she often referred to as "Boy."
