The TES modding community will figure it out. You really can't sell them short.

TES clothing models are vastly more simple than these models. I suspect simple clothing will be made but really detailed high quality stuff that meets the requirements to fit into the aesthetic will be rare.

I've been hanging around the edges of hte TES modding scene for twenty years now. They will have skin-tight space suits within 8 hours of the GECK dropping. Space bikinis in maybe 8.25.

Oh absolutely this will happen the fastest. In particular because it's the simplest content to make. Very few polygons are needed in a bikini.

If I had any chops on the 3d side of things what I'd do is go steal Cyberpunk 2077's models. 90% of them won't fit in but a couple will work.

Honestly I think modding will focus most around regular clothing rather than armour, space suits and helmets because those things are way harder to make and the standard in game is pretty high, with clutter detail all over the outfits that are a bit beyond non-professional work in my opinion. We'll see though. Regular clothing on the other hand anyone can learn to make especially as it all already exists.
