Doctor Who: Charlotte Elspeth Pollard, a.k.a. "Charley," the Eighth Doctor's Companion in the Big Finish Audio Adventures
In the Big Finish audio adventure "Storm Warning," Charley disguises herself as part of the R101 crew, so a uniform of some sort seemed appropriate for her. This costume is based on pictures from "Chimes of Midnight," pictures of wide-legged trousers for women in the 1930s (since the Doctor met Charley in 1930), and the top from a dress from the turn of the century, since it looked like it could be part of a uniform. I used a Butterick pattern for the top, and combined patterns from Vogue and Simplicity for the trousers.
