For Season 5 of Supergirl, Kara sports a new costume. From TV Line: "Supergirl Ditches Her Skirt for Pants in New Season 5 Costume — First Look"
The Super-costume definitely needs the red trunks to break up all the blue. DC itself recently learned this lesson after having Clark ditch the trunks for several years, only to bring them back again last year.. It's too bad that Greg Berlanti Productions/ Warner Bros. Television weren't paying attention.
Maybe if they went with red pants and blue boots?

I'm not a fan of that picture either -- hopefully it'll look better in action. I think adding some red elements would help, too.
