Star Trek originally showed all aliens as in some sort of uniform.
Overweight people do not look particularly good in leotards, but they look better than they do naked.

I suppose that in places where adults have veto rights over children's costumes, Hallowe'en will be more boring. The fundamentalists are against Hallowe'en completely: they consider it to be anti-Christian, anti-Biblical and satanic.
Adults at Waikiki will continue to wear whatever the Hell they want, as well as to strut around buck naked. There were lots of cops, and they did not do more than just stand about and occasionally direct traffic.
There was a most memorable scene in which a guy with a Satan suit on stilts met another guy, also on stilts, in a St. Michael the Archangel costume, complete with wings, robe and halo. They embraced there and posed for hundreds of photos. Both of them was about 7½ feet tall. It was most impressive.
There were about 8 people also people in banana suits that teamed up and marched together. There were 4 Marios and 2 Luigis that posed on the corner hooting at girls dressed as princesses.
Hallowe'en on Waikiki is NOT BORING.
