1970s Vintage Mod Yellow Courreges Courrēges Paris Sleeveless Print Zip Sweater

Iconic early 1970s bright, sunny yellow Courrēges sleeveless sweater with front partial zip (zipper is large-tooth white plastic with white metal pull) and a white 'X' pattern overall in a different thread. Ribbed trim at sleeves, neck and hem. White raised embroidered Courrēges logo is in the center, just under the zipper - Fabric composition is 91% acrylic & 1% polyamide; the body of the sweater is acrylic, and the white pattern and trim are boucle polyamide knit - you can discern the difference in thread texture between the two, which adds a subtle but very nice contrast between shiny & matte, smooth & crinkly. Satin label indicates there is also 100% cotton ornament/garniture, which must be in reference to the thread used to embroider the logo . The care instructions direct that it be hand washed only & laid flat to dry - no iron (which i suspect would melt it instantly). Size is a woman's small, or "A" - it looks like a small, although can successfully be worn by a medium; I tried it on and found that it fit me nicely (I'm a US size 6-8). In amazing, clean, damage-free condition with no snags, discoloration or other problems - a true find!
