Precisely. If one comes up with compelling logic for the costume, then you're more capable to make changes that everyone can agree are cool because there's a reason for them besides the entirely subjective, "it just looks good."
The question is, what's the most compelling reason one can invent for why Superman wears a costume? Personally, all the ideas that writers have come up with to fill this gap have been lackluster imo.
