Writing How do you describe physical appearances?

Once a character is introduced, we usually never talk about his clothes unless it's a drastic change

Yeah, but I kinda hate it.

If it is important, has some symbolic meaning or will serve some purpose for the future, I describe the appearance in one sentence at most. If not, I just let the reader imagine the rest.
