small boy's vest, pants & jacket (Greenwood)

This is a beige pin-striped double-breasted boy's three piece Yves St Laurent suit, a couple of decades old. The pants and vest are in wonderful condition, approximately a 19" waist, length about 25.5". Sadly, the little jacket got some spots on it while hanging in the closet. I tried to wash them out, and had some success, but did not have it dry cleaned. Maybe dry cleaning would do the trick. I loved this suit but the boy who wore it is 38 years old now.
