And later costumes weren't bulletproof at all.

Not at all, since pyjamas are essentially what Batman wore in the comics for decades. It's only since Dark Knight Returns and Year One, that body armour has played any part in his standard costume. Prior to that he wore fabric, even in your much mentioned classics like "Daughter of the Demon". Heck even Robin didn't get body armour in his tunic until the second iteration of Jason Todd.

That doesn't actually make any sense as a sentence, since uniforms ARE clothes.
