Picture of a red-haired girl from old (maybe 80s) anime
This seems to be Tiffany from Robby the rascal, also known as cybot robotchi or in Italian as Robottino. It was originally broadcasted by TV tokyo from 7 october, 1982 till the 29th of June in 1983.

the English version deleted much of the risqué humor that, while not uncommon in children's animation in Japan, would be considered unacceptable by American standards, with the policewoman Sachiko (Sgt. Sally) being the usual target of the fan service-oriented humor. The TV series also aired in its entirety in Italy under the title Robottino ("Little robot"), and some episodes are also available in Spanish as Robotete.



The Image the OP provided also comes from a fan-service scene, which can be seen here
