Glamourous vintage ivory sequin sweater set, handmade shrug and shell

Stunning sequin sweater set. Knitted and sewn in the 1960s by my late grandmother, a professional seamstress. Stylish shrug sweater is lined and has a retro rhinestone hooked closure at the waist. Shell underneath is sleeveless with a cinched fitted waist (inside elastic pictured above) and a zipper in the back. Both shell and sweater could be worn as separates. White color vibrancy somewhat faded but in excellent condition. Would best fit a short-waisted size 6 or a petite person. I'm a regular short-waisted size 8 (modeling in this pic) and the waist clasp on the shrug is pulling although the shell fits comfortably.
