Help Dating Christian Dior Umbrella Please

Hi, I recently picked up this Christian Dior umbrella in an auction lot of mixed umbrellas and am struggling to find any info / rough date for it. The pattern makes me think of the 80s however the actual structure / feel of the umbrella is more 60s (the rest of the umbrellas in the lot were 50s / 60s). Has anyone any idea what age it is please? Thank you
