It would be a bit of a useless accessory if it didn't. If it's all to scale then it might just about fit, like it definitely fits on the Deborah action figure, and I'm pretty tall, and very unslight. Not as big as colin, admittedly, but I'm sure we could make the dress stretchy, nothing people would like more than a tighter than skintight spandex dress stretched over an overweight middle age man, now in action figure form. The queues would be out the door.
Like they'd be running out of the door and down the street as fast as they could, as soon as they saw it.
