So what is a screen used costume??

Here is a little 'trek' educational info for those of you are not familiar with the costumes. The costumes that Steve and I will be wearing at the wedding are 'screen used' from two of the Star Trek television series. Steve's costume is from the 5th Star Trek series, Enterprise, and is worn by a Vulcan ambassador to earth in the first appearance, in First Flight, it is used again in Kir Shara, by a Vulcan politician.

My costume, is used only once in the 4th series, Voyager, and used as a holographic Vulcan character, in the episode Darkling.
Both costumes are pictured on screen in the pictures here.
