EUC Sz. M Meas taken lying flat 16-1/2"B/23"L 100% viscose shell 100% cotton trim around halter and 2" top of bustline. I just love this top, especially it's halter with the brown beading.. the way it frames your neck and face! The body of the top is double fabric with both layers fairly sheer giving a very flowy feel when you're walking. The halter fastens with 3 hook & eyes. Left side zipper.
