6. Supergirl

Supergirl is just so wonderful and wholesome and charming. It's like everything I love about the Flash but with all the goodness of the Superman universe.

And their Supergirl costume is pretty perfect. It's an exact translation of the comic book to screen with, like, maybe one exception, that being the chest emblem, but that makes sense. This costume is a little more navy blue and crimson than the traditional bright red blue and yellow. But that works better for TV so who am I to judge?

The Superman outfit is also phenomenal but we haven't seen it that much and it's riffing pretty heavily off the Supergirl suit. So putting that on here over this would be wrong. I'm impressed they pulled off the skirt as a part of the costume in a way that feels functional and not just a call to sex appeal.

What a good costume.
