Sylvia Ann formal beaded and sequined blouse. The size is faded on the tag - measures to be about a medium or a 10/12- please see the measurements and compare them to a blouse you love the fit of!! I think this is from the 70s or at the latest the 1980s! I think it may have been just hanging around in a closet for many years, but it is in excellent condition!!
