Vintage Ann Taylor Black Fair Isle Button-Up Cardigan with Burgundy Accents

Vintage Fair Isle knit cardigan by Ann Taylor. Appears to be 80s based on the style of the label and feels like wool. Size tag is missing, fits like a M. Black base with burgundy, cream, blue and yellow patterned accents. Front button closure with gorgeous mother-of-pearl buttons. Long sleeves and ribbed cuffs. Warm, classic layering piece. There is one pull on the black part of the left sleeve (see fourth photo) but it’s not noticeable, just wanted to be transparent.
