What you are seeing is what you see when the material for the clothing you are using is not available in the proper place. It's the "texture not found" look.
I'm not sure what version of MH you are using, but I can confirm that this is the result with version 1.3.0 on Windows. Apparently, this version does not download the built in assets and has only 2 assets under clothes in the community tab (, one of which is the t-shirt. )
It may be that if you find and download MH version 1.2 which is the "release version" that you will have better luck. Assuming you are on windows the link would be here:

node id 3508 WojackOWL CC-BY T Shirt A Basic Plane T-Shirt. So, it is a problem with that asset itself. But with this version you can see all the community assets. Try looking for Joel Palmius CC0 Crude Female T-Shirt which looks similar if not identical and has a material that seems to work fine.
