Vintage Melody Orlon sweater

I have been wearing ng this classic cardigan for the past three decades, and it was aquired at a vintage shop in NYC then! There is one button missing, I will have to see if I set it aside or if it is lost. These amazingly delicate ornate flowers are adored with rhinestones. They would show best if pressed. Is it time for you to enjoy this for the next several decades? Untagged for size Pit to pit 20 inches
