Behind the scenes
Cosplay was a significant activity within Doctor Who fandom in which people dressed up as characters from the show, typically at conventions, but potentially also at Halloween, fancy dress parties, or even for no particular occasion at all.

Fans' level of participation varied, from people who bought off-the-peg, pre-made costumes, to those who paid others to manufacture bespoke costumes, to those who designed and crafted unique items from initial sketches to finished product.

Starting with DWM 522, Christel Dee gave cosplay tips for costumes of several characters, such as Ace's jacket, the Doctor's scarf and a Time Lord collar.
