Available in Small, Medium, Large and Extra Large, they cost £15.99 each.
I haven’t seen them yet first-hand, but I gather the print quality isn’t all that.
Again these are available through Forbidden Planet, at £39.99 each.
I wouldn’t exceptions too high – not for £40. They look to be not much more than Halloween-style fancy dress costumes and definitely not day-to-day wear!
That said, they are good value for money if you need a quick and cheap costume for an up-coming convention of Who-related event.
