Vintage 80's 90's M brown purple geometric silky long sleeve button blouse top

Vintage 80's 90's size M brown and purple geometric silky long sleeve blouse top by Porterhouse! Buttons up the front. Has collar. Soft and silky. One front pocket. Rich dark purple with golden brown geometric pattern. It makes the top an overall brown color. Sleeve ends button. Just pulled from my closet as it's too roomy on me. Maybe saved it because my last name is Porter lol. It's really flattering on though. Wonderful. Happy to answer any questions ♡♡ Measurements: Pit to pit - 19 1/2 inches across. Length from shoulder to hem - 26 inches.
