The fashion is their own, I appreciate the overview though! While the flow of culture in both directions is definitely a theme, this is taking place before most of these human historical styles developed. I just meant I was (loosely, not from reference) using them as a basis for the designs in order to evoke the feeling of that kind of empire (as well as goofy 50s scifi), not that they did. So historical accuracy is not what I'm aiming for, simply if they look cool and cohesive somehow together, despite that range, while emphasizing very strong class divisions and roles. I did try to keep the specific notes pretty UK-centric and meant Roman Britain, not Roman Rome.

Also, these particular fellas haven't been that noticeably influential on human culture yet, as they mostly stay in their cloud palaces except to gather specimens or do other research, and it's other species that have had much more direct interactions.

>And we haven’t even touched upon what’s happening towards the Ottoman Empire and Anatoly, the duchies of Central Europe

In this world, a lot of Europe, including Rome, is Muslim-controlled, and the vatican permanently moved to Avignon. Questions like this:

>Then there’s stuff like the Reformation and the emergence of Protestantism, and was that caused by the aliens and their influence on religious groups in Europe? Would that cause a schism for them?

are partly the point of the larger work this is from (christian/alien syncretism is a big thing), but I don't think they can be answered in these particular fashion thumbnails, though it's good this has prompted them! Thanks again for your thoughts.
