Asside from the standard vault dweller uniform of coveralls and a pipboy 3000 John's got a Leather jacket with a big yellow 24 with red outlines on the back.

Biography: Johnny B. Elwood was what some people could call a problem child, others would call him a good child, up in the air really, depended on how well you knew him. Johnny had two problems really. his horrendous luck, and his tendency to get a little "friendly" with members of the opposite sex. Johnny had short flings with a few girls to be blunt. Being born in the vault was a bit of a blessing and a curse. some people looked at him with tented glasses in a respect. his parents both vault physicians. one would expect science, math, technology and the urge to mend people's wounds were in his blood! but yeah no. only thing his blood had in it was music as far as anyone was concerned. well music and ideas of getting into pants, lots of pants or so people thought. in reality it was just the pants of three individuals. First there was jenny in the diner, then there was sara down in laundry. and then there was susan. when these three soon got boyfriends near the end of the goat, three very jealous boyfriends and the friendly "visits" didn't stop, the overseer of course had to take a bit of action. rather than have a brawl erupt in any of those places because Johnny was a little too good, John was delegated to jukebox repair through careful manipulation of the computer code.  John's luck though is also quite bad. sure melt downs happen, things go boom, things break in a spectacular manner. but of all the people to walk into those rooms right when that stuff happens, 9 times out of 10 it's john. If ever a vitomatic vigor machine was gonna give someone a luck score of 1.... john would be the first in line to get that score. 
Other: Johnny was also considered for several other positions in  the vault such as the Fry Cook, the laundry cannon operator, and including Pedicurist. However one of the overseers had a hand in his posting in order to avoid conflict in the vault. When his test scores were submitted  the terminal "crashed", allowing the overseer to "rewrite" his scores which  set him as a jukebox technician.
