He wears trunks and tights in the recent film. The tights are heavier, and marred by stupid New 52 lines, which end up looking like padded panels, but they’re skin-tight and stretchy. I don’t see how short pants are an improvement. If anything, they look like he couldn’t find his trunks and had to improvise. Mixing street clothes and custom items like his boots and cape would border on the comical.
