This YSL dress is made of a fine wool jersey, it's fully lined features glossy black buttons. It buttons up to the neck and is a perfect example of understated elegance. It has no tags but I never wore it. My sister worked for YSL through the 1980's and into the 90's so I went to every sample sale there was! There is a Bergdorf Goodman tag between the dress and the lining so it must have spent time at that iconic store! The dress measures 36" bust, 36" hips , 34" length and the sleeves are 23' long. It is a French size 38.
