This is an iconic and classic look from the Rive Gauche collection. I have dated this one to the 1977 collection based on the version of the label and print that is similar to the one in the reference photo I have included here. That shot was used for the ad campaign that year.

These are so easy to wear and very comfortable. You just slip this on and you are ready to go. This can also be belted to add shaped and bring the length up which gives the dress a lot of versatility and styling options. They are a play on the smock style dress combine with that classic Yves Saint Laurent signature style of this time period. This one is made out of a scarf weight silk that is a soft and fluid silk. Around the neckline is a black cotton velvet bib that is edged with cording and closes at the very front with five glossy black domed buttons. The sleeves are full and ballon out above their velvet trimmed cuffs. The body of the dress is cut loose and easy with a low dropped seam to separate out the skirt and to tie all the velvet parts together. The skirt is constructed with lots of fullness so that it has a little extra swing. It really transforms when on an actual body. This is classic YSL and a great piece of fashion history. Excellent condition

Unlined and slips on to wear. Buttons at the neck with five button and loops. Pockets on each hip t the seams. tagged a 36 bit the cut is generous so should fit a range of sizes. Meant to be oversized on the body.
