Cute Czech actress Miroslava Šafránková starred in the main role in the German TV-series JOKEI MONIKA from 1981. The show was produced by Eastern Germany TV. Miroslava wore a denim on denim outfit with blue jeans and denim vest in two episodes with variations of the top below the vest (episodes 4 and 6). I have seen more women in denim vests in the episodes, but except the performance of Roswitha Marks it were only appearances below the half of a second, unclear in the background or unclear because of motion.
First pictures come from episode 4, they follow the chronological order of the episode mainly, but not in detail.
Second part of pictures come from episode 6, they also follow the chronological order of the episode mainly, but not in detail.
