Yup, that’s what I’m saying, where plate armor is concerned, I expect some amount of bulk, and thus some big guy (or woman) inside the armor. A tough dwarf should qualify as a “big guy” in this case 😉 but yes, I do see some stout fella when I think about it. 😉
Now, for chain or scale armor, things may be somewhat different since, at least, the armor itself can be be more “form fitting” in a way. And thus “less bulky” if not “less heavy”. 🙂
Hence Red Sonja’s notorious Scalemail Bikini, which R.E. Howard never described. Enough said about bikini armours. I’m staying off that topic, no worry. 🙂
