Marvel is Gender-bending Thor!

[Sithdarth]

Real world tactical considerations for Thor would probably just be a comfortable shirt and pants that are easy to move in and breath well, as anything that can hurt Thor isn't getting stopped by steel, anyway.

I thought Asgardians have super special magical metals or something. I mean they have the Uru stuff that they make weapons out of (like Thor's hammer and realistically probably some armor pieces) and whatever The Destroyer armor is made from. Also, I imagine that the Dwarfs are in general way better at making super strong metal than humans and of course there is the magic thing.

All in all I think it is safe to assume that any armor an Asgardian god would decided to wear probably offers some measure of protection even if it is only minor.
