This is a jacket by Ben Zuckerman, once part of a set made up of either a dress or a skirt. The jacket is very formal and is made up of very luxurious material- probably a silk/wool blend. The jacket is slightly nipped at the waist and is futher pulled in by a mock belt in the back. The buttons are decorative and made of rhinestones and there are even pockets at the waistline.
