I too have been working on clothing, particularly focusing on the deviations between the houses when it comes to dress.
First, I came up with some house clothing trends based on my research and created a bunch of concepts:
They are numbered for easy reference, and each marked with the capital letter of which house they would belong to (D for Dres, R for Redoran etc.). Originally I was planning to refine these concepts a good deal further, but after getting a feel for it and receiving feedback from Denevir and Dragomir, I decided to move on to other clothing concepts, focusing more critically on a characters outfit such as this Hlaalu Caravan Leader (normally he would ride a guar):
Now I plan to use what I've learned about house styles to elaborate further on my original concepts in a similar singular studies to the Hlaalu Traveler above. And I plan to focus on these aspects in particular as I might not have captured them best in the first drawings:
-Making the shapes and patterns (in particular the decorative pauldrons) reflect house trends eg. Curled intricate shapes for Telvanni, smooth, rounded shapes with western influences for Hlaalu.
-Investigating jewelry and other Dunmer accessories (goggles, belts, hats, wraps).
-Capturing the looks of certain jobs and figures within their societies. Give them some characterization for fun.
-And WOMEN. How do the styles change between genders?
Of course any feedback is welcome, and I will add to this thread when I have more :)

Just to clarify after talking
Just to clarify after talking to a concerned member- The majority of these clothes are expensive or even exquisite class (in the case of the Indoril), hence their ornateness and complexity (it would be woven from spider silk). A couple of the Redoran and Hlaalu are more simply dressed because they hold lower stations within their house. The Dunmer are a proud and arrogant people, so it is not surprising that the nobles would flaunt their wealth and influence. There are a couple of other concept artists that are already working on the important middle and lower class side of things, but I do plan to do a couple of simpler outfits for more practical work such as the Redoran Ashwalker/Messenger (non-armored) I have planned next.
