Called Rayadillo, these were specially designed to be comfortable for soldiers in tropical environments. Most versions allowed the butttons to be removed (they were held on by a ring similar to key rings) anyway the problem is painting the raydillo, which is usually white with blue or black thin stripes that from a distance looks like a hazy blue. the Spanish used many variations even within units, so that it can be hard to get a feel for correct uniform colors. most people just paint a solid light blue...but to PROPERLY represent it with super thin lines would be the most correct.
transgender-like priests of Inana were the Gala. they socially became women, at least some underwent surgical alteration. they had a role in religious sexual ritual and as singers at weddings and the like. it's a vague, but also fascinating facet of antiquity. and in a sense they are a kind of spiritual ancestor to my own existence. https://hornet.com/stories/sad-songs-and-buttsex-the-gala-priests-of-ancient-sumer/
