Wraithful Shinnok (My favorite outfit in the game)
Tournament Scorpion
Tournament Kano

That's it really as of now. Once dlc skins come out ill add a updated list.

Kitana - Base Assasin
Mileena - Base P2 colours
Sonya - Tournament P2 colours
Raiden - Tournament
Scorpion - Base P2 colour

Yes.

Probably the best costume in the whole game, I really like what they did with Shinnok's Wraithful costume.

Maybe Main,as my only gripe with Revenant is that Lao's bald(and it really looks odd for some reason) and the Tournament one doesn't feel as fresh as the Main one. Even then,I might go with Klassic,once it's released.
Liu Kang = Main(might be replaced with Klassic)
Mileena = Main
Quan Chi = Main(might be replaced with Klassic)
Raiden = Future
Shinnok = Wrathful

I'd like to participate in this thread, but I'm just very salty at the fact that the vet's alt costumes are either their MK9 primaries or retarded versions of themselves (i.e ninja mime Johnny).

I gotta say thought that maskless Sub-Zero is extremely boss this time around.

I love how OP left Scorpion off and most are just copy and pasting and completely forgetting about the Costume King

My overall favorites are:

Kung Lao: Tournament, Revenant
Liu Kang: Dark Emperor
Mileena: Kahnum
Kenshi: Ronin
Shinnok: Second outfit
Subzero: Revenant
Kitana: Dark Empress
Reptile: Tournament
Jax: Tournament
Johnny Cage: Hotshot
