Sure, but I meant sending them an email, cause even if you had access to their forum, there would likely be a hundred and one different interpretations of what is and isn't allowed. The only way to get official clarification, is to write to them directly and tell them what you were hoping to do with the personal licence.

The answer they give might even surprise all of us, especially since blender devs are now gearing-up to work on cloth dynamics etc. You can bet yer life they've got a close eye on blender, cause eventually, it is likely to have something that will rival Marvelous Designer, and if/when that happens, the company that owns Marvelous Designer will have a very different attitude with regards pricing and licensing (prices could plummet dramatically and licensing become more relaxed due to healthy competition).

The same thing will happen to Substance Painter once the blender-based PBR painting tool "ArmorPaint" becomes more and more capable. Adobe sucked-up Substance Painter, so this will make subscription-free ArmorPaint even more desirable. The Marvelous Designer situation will be no different, in fact, don't be surprised if Marvelous Designer is the next product that Adobe sucks-up.

BTW, here's ArmorPaint, the free PBR painting tool just in case you've not come across it yet:
