Vintage Fiorucci Dress 1960s? 1970s?

Found this in an upscale vintage store and thought I’d wear the heck out of it, but my commute and work situation have changed. I think this might be from the late 1960s when the label was first founded. If you have any ideas on the year, leave a comment below! The buttons are mint green plastic, black rayon with light beige dots. Pockets on the side seam. Mid-length. Pleats on the bodice. Excellent condition. Would look amazing with Docs. A note on the sizing: this is a 38 Italian which should be tiny. But I’m a contemporary 42 and it fit nicely (slim on top, roomy from the waist down). So this accommodates a range of sizes depending on how “oversized” you want it to fit.
