This top has hook and eye closer so can also be worn.  The label states Marlene's Golden Hanger 100% Silk, 100% Silk lining.  There is no size tag but i'm showing pics to give measurements. suggest it is a M, though I could wear it loose fit and am X small.  It has a Gatsby 20's look.  It is handmade with pearl beading and Silver pieces,  It is singularly beautiful and.true vintage piece. I've included a picture of the back of neck where silver beading has a couple that look missing but is not really noticeable and is on upper back,  I am also showing a pic where I've tossed it on to give a size idea on an xs woman.
