Vintage 80's long sleeve dress / costume

This is such a fun piece! The fabric is thick (definitely a winter dress or costume) made of genuine cow split leather. The trim is 90% acrylic and 10% acetate. Lining is 100% acetate. The piece is old and definitely needs a little love. Overall In great condition! It says medium in the tag but it runs small! Bust:30-32" Waist: 24" Length: 32"
