As part of Alasdair's Chicago visit, we take an hour to talk all about dressing up like Doctor Who characters, and who better to bring in for such a chat than cosplay maestro Kate Kulzick? Alasdair reveals he's doing a Halloween costume for the first time in about 15 years, and he's mostly doing it because it's super easy to justify the 9th Doctor's clothes as stuff he'll just add to his regular wardrobe. We then break down the pros and cons of dressing up like other Doctors, the gendered differences in cosplay, and how it's damn near impossible to dress up like most of the companions in a way that anyone will be able to tell who you're supposed to be.
