Eh, give it a shot if you want. If I like it enough, I'll even includie it in the Lore I'm developing for the race!

Well, the Ardent, being the closest thing that the Storm Elves have to a regular priesthood (and thus being the most likely to build and dedicate shrines and temples and set up doctrines), are near-fanatic nudists. They don't wear any clothing themselves, and you can bet that any shrine of temple they raise will have a "Leave Your Clothing and Weapons at the Door" rule. Which wouldn't be the case with a shrine built and run by Shamans (they don't care what other people wear - they just don't wear anything but body paint themselves).

As for the Hunters puting on loinclothes or pants when they get to town: Not in the starting area as the villages their don't even sell armor or clothing items to hunters before they reach tenth level. This is mostly due to having similar feelings of being more closely tied to nature through nudity, and pressure from the Ardent on local merchants because they are aware of this fact and want to promote spontaneous Druid creation. The merchants and Hunters don't mind this too much, as the Ardent's goals are laudable, but the consensus is that ten levels is long enough to find out if someone is going to become a Druid instead of a Hunter. After ten levels, Storm Elf Hunters' attitudes towards clothing turns from devoted nudism to practical consessions as they are ready to leave the areas of weak monsters and nonabrasive plants. Pretty much, a Hunter's first contact with thistles or thorns puts an end to their not wearing shoes away from towns, and with shoes they generally start girding their loins as well.

Once away from the starting region, where they start encountering other races more frequently, you would probably see the attitudes shift to what you've just described: Toplessness noticed slightly (and not in a negative manner), with nudity barely getting any further attention (from other Storm Elves anyway). However, actual bottomlessness (where the loin is left specifically bare despite wearing a top) would most likely be viewed as being deliberately vulgar and provocative, and thus frowned upon. Even by Shamans and the Ardent, who would be of the opinion of "take the rest off or cover that thing up, you freak!"

Do note that merchants in the starting region (and only in the starting region) do not sell clothing or armor to Hunters of other races either - if their Hunters can't buy such gear there, then neither can anybody elses Hunters...

Probably.

Might be a while though.

And I'm still welcoming creative input (costume ideas, perhaps someone drawing how the [i]males[/i] dress, ponderings of what their hodgepodge architecture looks like...).

It doesn't have to be pictures. Comments, discussions, or even a simple "yes this, no that, or how about..."
