Vintage Nordstrom Regency Collection For Joyce Blue Sparkly Vest And Pants NWT

Very pretty and sparkly in a dusty light blue color. The vest is a medium, and the pull on pants are a small. My best guess is this set is in a late 70s to early 80s style. There's one hook and eye closure on the vest. There's some stretch to the fabric.
