Vintage 1960's Joseph Magnin Knit Lace Trim Cardigan/sweater With Buttons

Vintage joseph magnin cardigan style knit sweater with lace detailing and pearly buttons. I believe it's from the 60s. My grandmother had gotten it from a friend a long time ago, and it's just been hung up for decades. It's so beautiful but doesn't fit me, and I know there are many vintage joseph magnin lovers. It doesn't say size but I believe it's a small/small medium. There are no stains just one small snag on arm shown in photo
