Well, there is tribalwear you can wear under the legionare and centureon armor, or the tribal kilt from Vanilla Apparal Expanded.

I think the rationale was that togas are basically supposed to be tribalwear+, providing very good benefit while taking a lot of slots. This puts them in line with mods such as 'onesies' which adds jumpsuits. That being said, a patch mod to make it a single layer would be welcome, if slightly busted. Although it provides no protection, even a cloth toga is enough to stave off heatstroke during a heatwave in arid shrubland, and frostbite in temperate forests.

What I don't love is that I just discovered that togas claim ALL layers- skin, middle, and outer- for near the whole body. This means no coats/capes/cloaks and NO ARMOR while wearing togas.

Were these intentionally coded to allow no other body clothing to be worn? If so, what was the rationale?

There wasn't a rationale. Sometimes, the folks in the Vanilla Expanded series just add something stupid, and refuse to elaborate further. This includes things like a Crown disabling ALL work and not just Dumb Labor, or a Jester Suit magically removing any ability to learn any Skill. Or, you can see the ever-enduring "no electric work bench because I'm an artist", which was actually said by one of the developers of this Mod series at one point.

If you want a better Mod focusing on classical antiquity, then you want Mlie's Ancient Rim Mod series.

Samuel Streamer once did a video with the AR Mod, but after VFEC came out, he tossed us aside like hot garbage and then disliked VFEC. He said that it and AR were not integrated, but they actually are. If you get my experimental Github branch of the Ancient Rim Mod's Medditerannean sub-Mod[www.github.com], you can also get full and total integration with the VFEC Mod.

Thanks a lot!
