What would happen if Star Wars and Star Trek universe collided? Would we see Borgs colluding with droids? Would Klingons take a R&R at the cantina? Most importantly where would the redshirt be? I think the answer to the last question is evident… standing as stormtroopers !
The research is fun, the sourcing is positively challenging, learning new skills always exciting, and seeing the completed work does make you proud… the only real constraint (aside from the money) is the space needed to store all the work done.
First you need to source all the parts, get them, build the costume, complete the accessories, check that everything is conform to standards, pack, unpack, dress up ( which in itself already demands specialist skills), go out, meet the crowd, try not to hurt yourself or anyone else since you cannot see anything when wearing a helmet, take hundreds of pictures acting in characters and most importantly do all of this in the worst possible discomfort.
There is also the “after trooping” side of things, when you go home and check for breakage and tears in the costume, the time spent fixing all the problems, ordering missing parts, improving the armour to make it more “comfortable” and/or upgrading some parts to fit with new guidelines and accuracy standards.
