*seizes the thread back from the coordination crowd to babble about clothes

Just checking in to say that I THINK I have the files for the dress done - human, elf, and dwarf - but I still need to check them in-game. I'll try to finish that bit up tomorrow.
Not sure if input is still sought or no, on what Alistair might wear, but I did give that some thought (and with apologies for all the images), andof the things already suggested, I think the retextured Orlesian noble hunting armour would be very appropriate, and coincidentally, since it the one in the image Luna chose, I suggest using either the texture I called "Highever"... the dark green cape is very flattering with Alistair's colouration (IMO),

or the blue one I called "Cousland", since it echos the Warden blue armour, without BEING the Warden blue armour. (If that makes sense...)

To include the armour in your archive, you'd need permission for the textures from Setiweb, as the "curator" of Aremeta's mods... The mesh/model, would either require Kirkwall Exports or permission from Amycus to distribute a standalone, retextured version of the port. (Something I was not able to obtain when I requested it, YMMV.)
For a more amour-y armour, and one that is more Ferelden, the vanilla Scale armour is visually attractive, a bit ornate, and the small pauldrons might not be a problem with the hugs-and-stuff.

Sans the helmet, of course... That's a test shot from my attempt to re-colour the set.
