I always have trouble dating Chinese clothing - it's very timeless to me! This set is really beautiful quality with a embossed? print of flora/fauna. Silk. Has a tag that just reads "made in china" and some hand-stitching and rolled hems. Mother of pearl buttons. I think the belt might be a bit higher than it should be - my mannequin has a long waist. Thoughts? I am not sure honestly... it seems older than 70s to me just because I've had many sets from the 70s and they don't seem as good quality and they seems more mass produced at that point. Thank you! Also - does anyone know of any resources to learn more about chinese clothing/textiles? It's interesting to me.
