Ant-Man concept artist, Andy Park, has shared another piece of concept are on Twitter, this time of his work that was ultimately redone for the final Wasp design.
Here is Park's later effort which more closely resembles The Wasp design used in Ant-Man.
The final choice for The Wasp's costume seems more consistent to the Ant-Man style although Park's talent is very impressive in all cases.
You can catch Ant-Man in Captain America: Civil War in May 2016. As for The Wasp, we'll have to wait and see.
