Here's a question if anyone has a solid answer..,
From what I've recalled/watched of the history of FFXIV[1.0]
There was a Smallclothes/underwear System where the variants of hempen small clothes was interchangeable..,
<til they unnecessarily locked it to races, and then shared two races sets with Hroth, and viera>

if such was the case..,[the fact that in the ancient system, people could wear either.., which is the question if that was true.., and if true]
there really is no reason why they can't give them today with some adjustments.[or changes to the name]
