I have had a similar suit in the ship from the 1982 collection that had the musical note patterns from that year. I believe that this is from the same collection. Aside from the different print the cut is identical to that one I had. The heart print is an important one for Yves and he used it first in the 1971 collection that has since become a cornerstone collection. I have included some reference photos here so that you can see the progression from that collection to this version of the print made eleven years after.

The set is made from a light weight black crepe that has a custom screened heart print that cover both pieces. The hearts give it a  whimsical feel that is balanced out by the stark white on black colorway. The skirt is banded at the waist with soft pleating and pockets on the sides. It is cut to skim over the hips and falls in a simple pencil shape from there. The top feels partway between a jacket and a top because of the fabric choice which is fairly light in weight. It is beautifully cut with soft shoulders and sleeves that are fuller through the upper arm and then narrow in at the wrist. Through the body is is cut with just a suggestion of the waist. It buttons to close and has his signature ribbon finish that runs around the collar and down the front edges. It is beautiful. Excellent condition.

The jacket is lined in a black silk with the sleeves left unlined. It closes with buttons at the front. The skirt is unlined and closes with a side zipper and button at the waist. It has hidden pockets on each hip. It is very light and more like wearing a dress then a structured suit.
