Tab sleeved animal print vneck blouse

SIZING IS A GUESS - PLEASE SEE MEASUREMENTS This animal print blouse has a vneck and button tabbed sleeves that are approximately half length - lots of great details. No care / size tag, otherwise EUC. Laying flat, armpit to armpit is about 20" across. Length is approx 27" to lowest point in front (hem is curved). Best guess is that this is a medium.
