Here is a brown cloak that Molly wears to the Hamleys in Episode 1.
When I saw this cloak, from Episode 3, I thought it might be the same one.
However, on closer examination, I began to think it probably is not the same one. Look at the way the fabric doubles back for a lining (the other one didn't look like that):
And no silk lining on the hood:I'm not sure of the material on this dress either.
I wonder if the second cloak might be re-created using View B of Butterick 4419. I am not sure about the first cloak though.
