It seems that the phrase is not commonly used. I just learned it from Hanna Montana and she was criticising her uncle's clothes. And I just want to know this phrase's first meaning without any any context.
I am sorry. We do not answer questions without context.
However, if you describe the scene in which it is used, I think that will be sufficient context to tell you what it means in this case. What was the uncle wearing? Was he dressed in fancy clothes? And so on.
