Re: By popular demand, the OOC thread...
Clothing... just about anything is possible in the way of styles. There are several thousand worlds which are members of the Imperium, and many of them (including over a hundred with human populations transplanted from Terra over 300,000 years ago) have very old cultures, and distinct fashions.
Shipboard clothes will tend to be simple and "sensible" - jumpsuits, coveralls, that sort of thing. You don't want to be trying to get into a vacc suit in a hurry, while wearing a ball gown. :p
Tunic and pants, often in a military "dress-uniform" style is also popular, particularly with crew who have to interact a lot with the passengers. Crew who've seen military service will sometimes wear their old uniform, or parts thereof.
Some engineers like to walk about the ship in bare feet - claim they can feel how the drives are doing from the vibrations in the deck. This may be superstition though, since the drive bearings are designed to deaden said vibrations. Then again, engineers hold conversations with their drives, and have even been known to give them birthday cards, so... *shrugs*
Equipment: I'll get back to everybody on that shortly. :) Simply put, everybody will get a spending allowance to buy stuff with.
