The images and costumes fit with other images that we have already seen, unsurprisingly, and seem to show Wonder Woman and Steve Trevor when they first arrive in the “real” world, and when they are attempting to form a plan or find out some sort of information.
We’ve already seen these costumes, and know that Wonder Woman will be teaming up with Steve Trevor — especially as that is a key part of her backstory.
We already know the basic premise of the movie — that Steve Trevor (Chris Pine) crash lands on Themyscira, and is returned to the world by Wonder Woman (Gal Gadot), who joins him during the First World War. Fans have already seen plenty of images of Wonder Woman and Trevor in “man’s world” during this time period, thanks to the trailer itself as well as various stills and promotional images.
One shows Wonder Woman in her Themyscirian costume and a black coat/fur, standing next to Trevor in a thick coat and sweater.
