Modeled after the Doctor’s police box time machine, the TARDIS ballroom dress was created by Kelldar, who is known by frequent convention goers for her awesome costuming skills.

Kelldar said the inspiration for the dress came after getting an incorrect shade of blue — “TARDIS Blue” as she called it — fabric for a Marie Antoinette dress she wanted to make. Rather than ship it back, she decided to go with it.
