They could use one, couldn't they? Too busy formulating and not enough time on making fashion statements....
It struck me that there are only three (or two) hairstyles - the buzzcut, with a few indents here and there, the bun and the ponytail (which may just be the bun coming undone). We're not certain if this is gender-specific, since at least one "he" wears his hair in a bun. Their bodies look asexual, as well - no bustlines visible.
They all appear to wear varieties of tunic as well. Did B5 not merit one, or did he discard his when he left town?
(Also, no children visible. Do they spring full grown from the forehead of the parent?)
