The game is pretty heavily populated now. Lots of people wear hoods or shrouds. While there are plenty of variable nouns, you're locked into having one size adjective. This can make working around shrouded people problematic as some commands don't accept ordinals. Yes, disguises should make things confusing or chaotic, but sometimes they also outright break stuff and this would be a good way to help make that less of an issue.
Basically, add a few adjectives for people to choose from based on their size. Other things like attractiveness could still override them as they do now. These don't need to be gendered, but the current existing ones could probably remain gendered.
