This is a 1980's Louis Feraud 2 piece ensemble that includes a blue and black plaid silk blouse and a black wool skirt with blue details on the waistband that match the skirt.
The skirt is nicely lined and has small pleats from the waistband. The blouse has shoulder pads and is double breasted with pretty silver tone buttons, long sleeves, pleated shoulders and a notched collar.
Marked size 6 but fits more like a modern day size 8.
BUST: 40" (meant to be blousy not fitted)
