No The Batman spoilers. This is just something that stuck out to me.
Obviously, you got glimpses of the suit in the trailer; but, the movie is deliberately paced and you have time to study the images. I noticed early on that the cape has a collar. Some people have commented on that being Bruce Wayne being stylish even as Batman.
Honestly, I saw the cape design as another push toward intimidation. It's like a modern version of what Dracula would be wearing.
What's more, this is not a stylish Bruce Wayne. In the few times that you see Bruce, he's kinda doing the bare minimum. Yeah, Bruce Wayne fell asleep during a board meeting in The Dark Knight; but, he fell asleep wearing a $10,000 suit. This new Bruce Wayne put on an ill-fitted t-shirt to meet with his accountants. He wears a suit to a big event; but, I'm pretty sure I've worn more expensive suits.
