vintage 100% silk ralph lauren blouse

This floral blouse is 100% silk and comes with a black polyester tank top to wear underneath. Both items are sheer but when worn together are not. I believe it is vintage from the 80s and it is in perfect condition. Here are some measurements of both items taken flat: tank top pit to pit- 17.5 inches length- 16 inches blouse pit to pit- 19.5 inches length- 22 inches shoulder to shoulder- 15 inches
