Because it would be weird if they all reappear naked once they get resurrected in Avengers 4 (if they do get resurrected, that is).

It doesn’t make sense. it would make more sense if they appear naked

It would be to complicated to make them naked when they return and I don’t think the actors want to and it is a PG movie so it would be a very weird movie with the superheroes naked.

The power that’s dusted them, can probably dust what they are wearing too. Some poor soul may have been in the shower when they got dusted. If they do reappear, hope they return to the shower.

I think Dragonnewt is a pervert.

He’s not wrong. Logically, their clothes shouldn’t have disappeared as well.

But from a directors view, having them naked in a PG-13 movie would just make it for mature audiences, and thus wouldn’t have grossed as much as it did due to less people being able to see it.

And yes, this does somewhat mean that the OP is a pervert.

We did see Hulk's butt in Thor: Ragnarok, so I'm pretty sure that PG-13 audiences are prepared.
