Still not a ton of options, and if you use custom morphs for the body they don't work for the clothes.
Typically if close from this or blendswap do not fit, since I do everything in blender, I can just reshape clothes. As for Daz content, I know sometime it can be exported to blender, but since most files are protected or paid for, people are not allowed to export these files to be shared so I have a hard time getting asses to any exported daz stuff, since I don't buy anything daz related. I have thought about using assets from the massive unity store, but most of them are too low res, and blender and obj is not the most common and supported formats on sites like turbo squid.
