Fighter - 42 Halloween Costume Ideas
Fighter costumes lean on fighting-game silhouettes, sharp, exaggerated, built for a specific stance more than everyday wear. Raiden's straw hat and robes, Kitana's fans, Johnny Cage's sunglasses-and-attitude combo, each one reads as a specific move waiting to happen.
A confident fighting stance in photos sells this more than any prop does. Practice one signature pose from the character before the party instead of just standing normally in the outfit.
No, one signature pose for photos is plenty, nobody expects a full performance.
A lot of it currently is, since the franchise has such a distinct roster, but it's not exclusive to one game.
Usually the accessories, fans, blades, specific gloves. The base outfit is often simpler than it looks.
