in fashion everything old is new again - Star Trek∶Website

Aren’t Odo’s clothes just…Odo? Like he’s not actually wearing anything. He just changes shape to make it appear like that.

Odo don’t need a closet, just a bucket.

Yes. He’s like plastic-man, in that he’s stark naked, and only looks like he’s wearing clothes.
I seem to remember an episode where he turns into a raven on the concourse and leaves a pile of clothes behind.
I believe that scene happens just after he gets his shape-shifting powers back; for a while before that, he had to wear regular clothes because he had been made more or less human as punishment by the Great Link.
