Costume or civilian clothes? (Arguably, she was romancing him, but she still stabbed him more times in this timeline than she's kissed him. Which is fine by me, he can definitely do better. 🤣)

That is *definitely* a costume. Civilian clothes, I would argue, as a general rule attempt to fit in with contemporary fashion trends. That's designed to stand out as far as possible. That boy wants to be seen!

See, I'd venture civilian clothes are 'clothes you're not likely (or looking) to fight in'. I mean, there's a difference between being publicity-minded and and being 'on duty'. At least every other time we've seen him wearing this, he was definitely not what I'd call officially 'on duty', though yeah, of *course* that boy wants to be seen. XD When your whole skillset is basically 'superhero' or 'ex-football player', branding is about all you got left to bring home the bacon!

Merriam-Webster defines "civilian" strictly as someone who is not in the armed or peacekeeping forces, and the United States Army recognizes "civilian clothes" as almost anything that isn't a defined uniform. Loosely speaking, most of DC's superheroes should be considered deputies of the law, and wear a uniform designating their special status to society-at-large. Therefore, a super hero wearing anything other than their IP trademarked outfit could be considered to be wearing "civilian clothes." I also concede all this would seem to apply to Booster here, as he is not obviously clad in his familiar 25th-century power-suit.

HOWEVER, Booster (1) isn't in the military, (2) has been known to change looks from time to time, and (3) is wearing an outfit clearly meant to evoke his traditional costume (and brand). Add that in this particular context, he is responding to Batman's summons wearing what you see, while all of his colleagues on the Justice League satellite are also dressed for "work." Booster is not shown changing outfits before going into action, so the presumption is that he is time travels to save the day in what he's already wearing. Therefore, even by your definition, I contend that he sure seems to be "looking to fight" in what you see him wearing here, so I will insist on calling it a costume (as I have before; see: "Los Angeles Casual" on the Boosterrific! list of power-suits) until such time as evidence in canon proves otherwise.

(I admit I'm probably being pointlessly argumentative on a purely semantic point, but "being pointlessly argumentative" is a key cornerstone in my personality matrix, and why else read superhero comic books if not to argue about their contents?)

Well, crud.

We wouldn't be comic book fans, buddy, if we didn't argue pointlessly about semantics. XD And anyway, who's to say they didn't summon him from a karaoke session anyway? He doesn't carry his powersuit in a ring, so it's entirely possible he got called to action while out doing non-hero things. Maybe he took a minute to change into the actual uniform/costume before time-traveling to save the world (again) after we see him vanish.

I can definitely say wearing civilian clothes (I suppose calling them street clothes also works) doesn't preclude a public servant (or possibly superhero) from going into action without the uniform when there's no time to run home and change into it. I was married to a rural police officer for many years, and many times he strapped his gunbelt on over his jeans and bolted out with his badge clipped to his belt. (And it's totally fine, really, to call this outfit a costume since we see it more than once and it's themed, but I think in-universe, it's probably really just one variation of Booster's street clothes. A 'notice who I am' outfit, sure, but still not meant for battle.)
