First of all, let’s set the record straight: they aren’t short shorts, they’re a leotard. Dick’s an acrobat. It makes sense.
Second, you wanna put Jason’s Robin in pants? Fine. He’s not an acrobat. The only reason they did in the first place was to make him look like Dick. I’m talking about the original Robin.
It just always seemed strange to be to put the first Robin in pants, at least in the comics. The leotard fits with his profession and allows greater flexability. Plus, it’s classic. Maybe have him grow into the idea of pants when he’s older to transition him into Nightwing, but a younger Dick Grayson should have a leotard.
That’s just my opinion. What’s yours?
