Cream and black striped varsity style cardigan

Cream and black varsity style cardigan. Vintage. Brand is Karen Kane. Striped sleeves. Has these really unique high slit pockets. Buttons are the kind that snap together. No marked size tag but I'd suggest for a petite medium since the sleeves are shorter than usual. Would be an oversized fit for the torso. Measures 22 inches wide (44 inches) by 29 inches long. Pit to pit is 23 inches across. Sleeves are 16 inches long. Please compare measurements to your own to make sure it fits. Used item, has been washed.
