>>45380875My shogun boyfriend likes useless oneesans and I don't fit the bill, though based on the things he's said about dating before I'm sure he'd fall in love with anybody regardless of that. Personally jiraikei isn't really my thing but he likes it enough to talk about wanting to wear those clothes himself so I guess I'd have to make that small sacrifice for a couple of hours. However the majority of his fans (and female japanese otakus in general) already dress that way for irl events so standing out would be difficult.
Slightly unrelated but I've thought about scenarios like that many times before and I take huge inspiration from the #スタライ参戦服 hashtag. Japanese enstarries are insanely fashionable and I could learn a thing or two from them, like ordering my own custom clothes such as pic related in the very rare chance a holopro/stars focused event happens near me.
