I don't have a ton, and I still have to photograph a couple, but here is the first one:
Season 1 Buck Rogers white jumpsuit

To my knowledge, this is the only white one in existence, and there is a story behind it. This was once the blue jumpsuit sold at the 2003 Profiles auction.
....wait, what?
All of Buck's season 1 white jumpers were dyed blue for season 2, including this one. After it was sold by Profiles, it was stored improperly somewhere along the way and the blue was horribly faded in bad shapes all over (imagine it being sloppily draped over a towel rack and set in the sun for a year). I figured I had two options: Have the color removed to even it out and have it redyed blue, or if all the color came out, leave it white. You can't simply bleach a costume as you will destroy it, so I sent it in to a conservatory to have the blotchy blue dye removed. It still has a light violet tint to it, but they didn't want to risk going further, and I agreed. I figure it can be dyed blue later if I wanted.
More later!
