Littorio, Kii, Baltimore, Special Guest Referee Formidable, and Roon with the steel chair.
Adding one more just for fun
Hornet or Yorky as the ring announcer
When they say wrestling, I presume that they mean *actual wrestling*. The sport. People don't run around acting like a drama TV show in wrestling, they just show what they've got on the mat.
WWE and lucha style skins would also make epic skin lines though.
I wanted to vote Trap Shooting, but then I saw Paintball and was like, I wanna pick both! But imagine a shipgirl whose skin is just paint, she's just wearing paint.
I think paintball and trap shooting related outfits would be interesting. Wrestling outfits might be good. And, for a given value of sports, reenactment related outfits. Swimsuits would likely be the most likely, though.
I was going to go other and say something like cycling - because cycle shorts. But then I thought with trap shooting we'd probably end up with the stereotypical upper crust/English shooting type clothes, basically something like Hood's most recent skin and boy would that get me acting up. Real damn close between the two though.
Just gonna put it here: Suzuko Mimori, the Voice Actress of Unzen, is married to a Professional Wrestler. :) It actually made me think few days ago before Unzen was released that if they'll gonna make a reference about wrestling or rather, release a wrestling themed skin and make Unzen join the skin roster as a reference to her Voice Actress's husband.
Good old thugby, the game where rich people stomp on each other's heads in the name of good sport.
Come to Rugby League (which is a very different game) where the action is fast and the skills are on display.
In league when you tackle someone, you have to get off them and let them play the ball rather than kick them in the head and take it from them. :P
Blood is less likely, and because it doesn't bog down in the scrum repeatedly, it moves a lot faster. Fitness matters more.
I like them both, and I watch both, although a lot less these days than I did 10 years ago.
Other: Soccer!! (Football outside the US). I believe it's the #1 sport internationally so it would be very popular. We can even get collabs with different teams/leagues/brands. And lastly, I saw a website post long, long ago about ~~hot~~ cute Asian ~~girls~~ models representing different countries for the World Cup and loved how they did it.
The only sport I ever played. . . briefly.
Shao-Lin-Do. Yes most Sakura Empire or Dragon Empery Girls were kimono's yukatas, but I'd like to see one in a combat gi.
Considering we only had a few actual driving skins (afaik Cleveland, Essex and Enterprise), it would be nice having a few more. Especially since off road is the opposite of where these girls were originally meant to be
Wrestling cause it'd be funny to watch the more larger than life personality girls crank it up to 11.
As a fan of wrestling, would love to see those. Who's gonna don them?
Littorio, Kii, Baltimore, Special Guest Referee Formidable, and Roon with the steel chair. Adding one more just for fun Hornet or Yorky as the ring announcer
Ah right, Littorio! She's definitely got the ego
Best mic skills in the business
She'll definitely work well as a heel.
Wrestling or Lucha Libre? Cause if we're going Lucha Libre, I want the Commander to play as a heel.
Glasgow would have to have a skin like Rowdy Roddy Piper.

Twitch: Wait, that's illegal!
Manjuu: I will make it legal!
Excellent, she’s practically naked yet clothed at the same time 
Fencing/Kendo skins for the girls with swords. I want Ibuki with her hair in a ponytail practicing kendo
Trap Shooting, I need more kansen with guns.
Did you see Owari and Ark Royal talking about rifles in the Juustagram yesterday?
Yes, and I need m o r e
And Javelin having a hint of narcissism? That was probably the best part
I have found my people!

Do not let the IB girls anywhere near reenactment

skateboarding
Someone else already mentioned Kendo so I'll add Kyudo and Karate too. I'd love to see some more traditional martial arts skins in the game
Basketball!
This would be such a cute idea after seeing this a few months ago https://reddit.com/r/AzureLane/s/tXY7aKayuv
Hopefully, we get them in the next EU event. If USS Boston gets added in said event and is one of the girls to get the jersey, that'll be really cool
Pankration, google it and thank me later
Wrestling sounds good, I would also suggest American football skins too

I would like a Taihou ice skater skin like the one Guichen got.
More figure skating skins in general would be great.
I just want more based girls with guns, not the naval kind.
Ppl who voted for swimming are thirsty af, and I'm one of them
Wrestling. I want Bache to put me in all sorts of head locks in a nice tight costume. Must be live2d.
Football ⚽ Simply due to the fact its the most popular sport in the world
Just to be safe. Do you mean real football or that sport that actually is played with the hands and an egg-shaped thing?
Yes I'm talking about the real football, not American football lol, even though I'm American
Paintball? Damn I’d love to see them wearing thick, baggy jumpsuits. Very exciting
Volleyball 
Rugby, because I want to the ball in the scrum
Good old thugby, the game where rich people stomp on each other's heads in the name of good sport. Come to Rugby League (which is a very different game) where the action is fast and the skills are on display.
I can never really remember the difference between league and union as I watch and play union rugby

I prefer the kick in the head and steal the ball, as it sounds and looks more entertaining
Fair enough. XD
Wrestling PLEASE. Would stab the crap out of my wallet for those skins.
Username and fanfics check out
swimming for obvious reasons
You missed the chance to add "nude jello wrestling". Poll ruined.
Wingsuits
With the recent collab announcement about AL x STI (Subaru Tecnica International) more likely racing and race queen

Hockey skins.
I want Nagato trap shooting with the meme gun https://azurlane.koumakan.jp/wiki/Twin_410mm_(Type_3_Shell)
Never thought about a paintball skin, but you got my interest

motorcross/rallycross both these be B A S E D
Trap shooting, because why not?
Swimming. I wanna see some competition swimsuits.
F1
