About Sci-fi Costumes

Sci-fi costumes lean on clean lines and tech details over anything textured or worn-in, Sombra's tactical tech, the Men in Black suits, Ellen Ripley's utilitarian gear. Sharp and functional beats messy every time in this genre.

A few well-placed tech accents, a visor, gloves, a chest piece, do more than an entire costume covered in gadgets. Pick one or two details and make them count.
