Vintage hot pink cardigan with pearly buttons

The brand, fabric and size of this sweater are lost to the ages! I know I have had it for decades, and I got it from someone else. It's soft, and likely a poly/acrylic blend. It doesn't shrink and doesn't wrinkle, so not cotton, etc. It's just a straight-forward simple cardigan that will never go out of style. Likely size XL.
