I commonly put loincloths on my fat or more monster looking characters but the only cases with a fat creature without a loincloth was because my slimes can wear anything because they can compress easily but that makes them heavier and more firm (I mean as a stiff body that isn’t easy to move, not the other term)
I mean I’ve put slimes in small clothes which makes them look slim but in reality when they take off their shirts or pants they become fatter than the fattest sumo wrestler in history (which commonly is how fat slimes are) basically a fun fact about the slime is that the fatter they are the healthier they are. Basically they can filter the nutrients and things that generally are unhealthy. The nutrients are turned into fat or in this case mucus and they can eat whenever they want (by that I mean they are never hungry and hungry at the same time, all the time as well) wait I’ve been rambling again..
