I know in my heart of hearts, Majesty was fujoing out seeing Sendhil and Niall like that, that entire trip about to get recorded as their own personal doujin
AMAZING reference chart put together by Nadeshico Rin, showing the different attires worn by the men of the buke class in and about Edo Castle. OP stresses the chart is by no means exhaustive - but it helps picturing things SO MUCH!
For easier reading, I have adapted the chart with english translation. Rin has also created illustrations detailing each attire, I'll translate those in coming days under the tag "samurai kimono".
In case it wasn't obvious, this is meme art. As such, it's far lower effort than my usual work. For example, the moon, city, and castle are copied directly from my "XIII" piece.
Basically, I thought of this joke since last week and only now did I think to express it. I couldn't sleep last night, I was thinking about this joke, and I got the urge to make it art. So, instead of trying to sleep (knowing full well it wouldn't be good), I made this. lol
