When fans met the DC Extended Universe version of Barry Allen (Ezra Miller), they were introduced to an inexperienced hero who was still growing accustomed to his super-speed powers. For that reason, Barry wasn't the expert we know from the comics, and this was clearly reflected by his Flash costume, which was of his own design.

Flash's costume was more bulky than in the comics, and it appeared to have more attached pieces to it, like you'd expect the home-made version of a teen superhero's costume to look. But now, we've learned that this wasn't always what Flash was supposed to look like in Batman v Superman and Justice League.

Concept artist Jerad S. Marantz released a few shots of his early design work on The Flash, which at the time was done prior to Batman v Superman. The artwork features a suit that is very similar to the one seen in the final product -- however, the key difference here is that this suit appears much less bulky than what we ultimately got. The streamlined version of this costume brings it that much closer to the comic book look, while keeping it very much ingrained in the gritty world of the DCEU.

The costume also appears to have more yellow highlights, which of course calls back to the comic book costume. Even the lighting bolt symbol on the chest appears in a more prominent manner, but there is actually no white circle behind it -- something that the cinematic suit did feature.

While this is not the costume that we saw The Flash wear on the big screen, something close to it could still be coming. After all, there was a rumor at the time that Bruce Wayne was supposed to give Barry Allen a new costume to wear in Justice League, or the planned Justice League - Part 2 movie that ultimately got scrapped.

Then again, there's always a chance that Ezra Miller's Flash will come to wear a more refined version of his costume when the character stars in his own solo movie, which is still expected to arrive some time in 2020.
