First, it would depend upon what sort of humanoid... and then how far removed from humans and civilization his race would normally live. A Frost Giant from Permia would not be expected to wear the layers of robes found in the Byzantine courts, for example... a couple of furs around the middle and he'd be in sartorial splendor for his kindred. Since D&D has half-orcs, and orcs have a reputation from Tolkien onward of scrounging armor bits, they should perhaps be able to wear some human clothing. Goblins are supposed to be smaller and trolls bigger. Ogres and Giants run on the XXXXXXXXXX...XL size. (I had to add the elipsis so that the post wouldn't be wider than most monitors.) In Norse mythology, trolls are a bit bigger but have been known to wear human clothes and disguise themselves as human (often for the purposes of trading babies). Those trolls have tails! and ears which hang to the ground!!! A troll woman wanting to take a job washing clothes for the royal palace must tie up her tail and wear a kerchief over her ears if she wants to get past the guards with her laundry basket. BTW, you do know how to tell if your baby is really a troll child? Carolly
