What my humanoid creatures wear, human, goblin, or otherwise, depends entirely on their culture, level of intelligence, and how industrious their area is. 

I once played a human tribesman who didn’t wear much more than the kobald posted above. Indigenous tribes tend to dress up both out of necessity and status. The ones in colder climates will wear furs to stay warm, while the ones in warmer areas wear practically nothing. I’m sure we’re all familiar with the feather war bonnets the chieftains wear so that they can be more easily spotted by their tribesman. 

I’ve also seen tabaxi (DnD’s version of a feline anthro for the uninitiated) who typically live in a tribe. But this one had grown up around industrial cities, where what you wore was both a status symbol and what separated you from the savages. They wore fine clothing to try and distinguish themselves as a member of the upper class. 

So what my humanoid characters wear doesn’t depend on their race at all. 

[sup][i]Also I apologize in advance if the idea was to get pictures of humanoids in interesting clothes, but I've GMed too many characters to pick just a few.[/i][/sup]
