I'm actually writing further parts of my background (mostly from Yelenas standpoint) and I'm struggeling with one point after I think I miss some information about Stormcast Eternals. I don't know where to post it, after this forum doesn't have a loresection, so I use my blog for this.
I have thought about, that some Stormcasts had come to my own continent (not through a realmgate) and now where trapped there until opening a gate to Azyr or dieing in combat. And they found surviving humans.
After we know, that Stormcast Eternals are modified humans (not ghosts in armour like the Thousand Sons in 40k) there is the point what a stormcast would wear as clothes, when not fighting in combat. I don't think that they wear there armour 24/7 (if there is something like constant time in AoS). We have read that stormcasts were fighting for days, weeks or more at the same battlefield, but even when they are nearly immortal they should have to eat and sleep some time (and I don't think that sleeping inside the armour is that confortable) and have to do some body hygiene (if they don't want to smell like worshippers of nurgle after some time).
Do they wear tunics, dresses or shirt and trousers? Is there some point of background I didn't know, after mostly reading Battletomes?
Another point is, what do Stormcasts Eternals wear underneath there armour. I think the only thing we know is, that they have those black cloth or rubber? parts beween there armourplates (mostly visible in the kneepart), so they can move. But I don't know if this is they parts are connected to the armour itself or if they are wearing some sort of bodysuit. It would be a little strange if the warrior would completely naked when stripping of the armourplates.
Perhaps somebody could help me with my questions. It would help me with my writing.
