In the dusty attic of her grandmother’s old house, Sarah stumbled upon a forgotten trunk filled with vintage clothes. Among them, she found a gorgeous silk dress from the 1920s, its fabric delicate and adorned with intricate embroidery.

This discovery ignited her curiosity about fashion history and the stories woven into each piece.
