According to new data from The RealReal, Rebag, Vestiaire Collective, Fashionphile, and eBay, 2026 has rewritten the hierarchy of investment-worthy handbags. Some classics are cooling (the Birkin’s growth has slowed to a modest 3%, per Vestiaire Collective), while others have exploded (The Row’s Margaux has nearly doubled in value). Minimalism is clearly in its prime: the Margaux’s quiet structure and scarcity (The Row no longer carries the style) have made it one of the most hunted bags in luxury resale.
