IT MIGHT not break the Internet the way the first #JaredLetoAsJoker costume reveal will. But today’s sneak-peek at your next costumed Supergirl could rival the online heat for last year’s reveal of your next costumed Wonder Woman (Gal Gadot in “Batman vs. Superman: Dawn of Justice”).

As CBS goes into production with its Supergirl pilot, the network released its first images of Melissa Benoist wearing the big “S.” The show is in the running to make the fall schedule.

And by the looks of it, famed costume designer Colleen Atwood has scored again by keeping the comic-book tints on the relatively darker side of the color scale.

Atwood, of course, is an 11-time Academy Award nominee (and three-time winner) who has teamed multiple times with Rob Marshall and Tim Burton, winning costume design statuettes for Marshall’s “Chicago” and “Memoirs of a Geisha,” and Burton’s “Alice in Wonderland.” (She was most recently nominated this year for “Into the Woods.”)

Atwood, in other words, is especially gifted at working in dark and sometimes cartoon-y tints. And she is on a roll lately, designing for such DC Entertainment properties as “Arrow” and “The Flash” — with Supergirl’s costume even evoking tones from the latter superhero’s Atwood-created style.

Apparently the high-booted, above-the-knee look will stay in vogue at the House of DC, as Supergirl gets boots cut much like those of the new Wonder Woman. The costume’s top is textured similar to “Man of Steel” mesh. And the new costume ditches the bright yellows from the shield worn by Helen Slater in the 1984 “Supergirl” film, though it retains the shape of the yellow belt (which has changed so frequently in the comic books).

Speaking of Slater, the former Supergirl/Kara Zor-El — like former Superman Dean Cain — will have an undisclosed role in the new show.

As CBS’s Supergirl, the newly blond Benoist will play Linda Danvers opposite co-stars Chyler Leigh, Calista Flockhart, Mehcad Brooks and David Harewood.

Greg Berlanti is executive producer on “Supergirl,” “Arrow” and “The Flash.”
