Yeah, Stahlrim matches up decently with the telvanni priest robe and hood, too bad you can only get them by killing the priests at the temple in RR...

For the Elvish, I honestly thing Miraak's robe would look best. 

And for the Falmer,  an Adept restoration robe should kinda match, it's hard finding "white" robes.

Hearthfire adds "Red Robes" which are possible gifts from your adopted children. I honk that would look great with ancient falmer. Link: http://elderscrolls.wikia.com/wiki/Red_Robes I also agree about Miraak's robes for Elven. Gold accents are great.

Oh wow I missed those, yeah they would! Nice find Vileo. 

Thanks. I've got a near-photographic memory for stuff like that. Don't ask me what I had for lunch yesterday though. xD
But yeah, red robes, ancient falmer stuffs, if you have a mod with the crown, you can use that. Auriel's shield, possibly dawnbreaker to keep the color scheme. Dawnbreaker is a great backup plan for this build because of the sheer number of enchantment charges that dang thing has. Runs nearly forever.

True. 

I find myself trying to incorporate the Wedding dress into an outfit just for fun... I can only see it going with daedric or maybe leather... 

I personally loathe Daedric armor. I like the jagged concept, in my artistic opinion it is poorly done. Also the part of me that hates being mainstream finds it to be grossly (in both definitions of the word) overused. Also, leather armor isn't attached to a smithing perk, so it's hard to get a decent AR on it.

*dark brotherhood spoiler*
You also have the gilded wristbands found on the Katariah in the Emperor's chambers.

I have yet to use a single Daedric armor piece lol...

Yeah but that's a loooooong ways... I wonder what works with the emperors outfit!
