Vintage Pastel Baby Blue Formal Dress

this was my mother-in-law's dress, bought in Montréal in the 70s. Kept in storage since then. Gorgeous dress in great condition, fits me, but unfortunately the torso is too short for me (my MIL is quite petite) Would work better for a woman 5'4 and under or with a short torso. no size tag so measurements are included. measurements laid flat 📏 pit to pit: 15.5 in / 39 cm waist: 12 in / 31 cm length: 56 in/ 142 cm
