Just curious about this, because I'm trying to figure out which armour is best suited for my bosmer but both elvish and glass armour look like they were made by either altmer or bosmer. I would guess glass is made by the Altmer because it's shinier and more magical looking but in Skyrim the thalmor wear Elvish. Maybe they made both?

If anyone knows, I would be grateful if you enlightened me. Thanks~

I'm pretty sure the Altmer made both. The Bosmer seem like they would wear fur or leather armor, as they are always traversing the woods and it seems like something a woodsman might wear.

This^
The Darkelves made loads of armor, though.

Also, the Bosmer, and if you consider them, Khajiit are the only southern mer races on Tamriel. The altmer would be western (or south west), and the dunmer would be northern.

As for armor a bosmer would wear, anything that came from an animal.

Khajiit are not mer

Eh, there's a bunch of creation myths that point out that they came from proto-bosmer, whose forms were kept stable during the instability of early Mundus due to Azura tying their form to the lunar lattice.

They are in a sense.
They were originally Bosmer and got changed into cats by Azura.
Why do you think the Altmer tolerate them in the Dominion?

Technically, they're mutated bosmer, just like the Orcs are mutated mer.

Well, all mer really are, save for the Altmer.
