Barbara Wright no relation to Polly, was a history teacher at Coal Hill school and a companion to the 1st Doctor.
Barbara became part of the first Tardis crew by accident, concerned by the strange responses, lack of knowledge about the modern era and top marks, Barbara persuaded fellow teacher Ian Chesterton to help her investigate the background of Susan Foreman, who was inexplicably living in a junk yard.
Barbara and Ian stumbled upon Susan and her Grandfather, and ended up being valuable parts of the Tardis crew.
Barbara had a caring relationship with Susan, she fell in love with Ian, and often butted heads with The Doctor, strong and independent of mind, she was a resourceful and modern companion.
The Chase is the last adventure for Barbara and Ian.
The shape of Barbara’s top is hard to find, but here it is in a range of colours.
When searching for this you are looking for a Funnel Neck or a Fisherman’s Smock style jumper.
