Which New X-Men writer's comic costumes inspired the team's season 2 outfits?

Grant Morrison's New X-Men comics inspired the X-Men's season 2 costumes.

The season's redesign draws on the sleek black outfits associated with Morrison's early-2000s run on New X-Men. The creative team connected the look to the season's themes and to Genosha, as well as to the “E Is for Extinction” storyline adapted in the first season. The costumes therefore function as visual storytelling, not merely as a modern fashion update.

Morrison began writing the retitled New X-Men in 2001, with artists including Frank Quitely helping establish its distinctive visual identity. The run shifted the team toward a school-and-social-mission setting and emphasized contemporary, streamlined clothing over brightly colored traditional uniforms. The answer is sometimes confused with Chris Claremont, whose influential writing shaped earlier X-Men eras, but the season 2 costume reference specifically points to Morrison's New X-Men.
