Amazing find! This Y2K luxurious olive green blouse by Burberry is soft and made lustrous satin. Details like the babydoll waist, ruching, ruffles and sleeves make this a special piece. I believe it is a small but look at the measurements as the size tag was missing. Burberry Prorsum was the name for Burberry’s high-end, luxury runway line from 1999-2015. Please note the area of the sleeve around the armpits. See pictures. The fabric appears to have pulled from wear and I am unsure of its repair. Button on sleeve has small pull at edge. Would not be seen when worn with a blazer or sweater.
