Anne Mari - 真理アンヌさん

 

This cute woman from Japan may be Anne Mari, who was promotion pictured in a denim on denim outfit while the 1970s (?). Not totally sure about that, it's not easy to find a way through those japanese websites, they always be mysterious to me.

Three, four, five and a half - שלוש, ארבע, חמש וחצי

 

This is episode 1 of  Israeli tv-show שלוש, ארבע, חמש וחצי from 1980. The woman with vest is Yona Elian - יונה אליאן . I'm not sure if it is really a denim vest, maybe only a vest. Not easier to discover after black and white tv is colorized later.
