Hello, everyone! And well met!
I have come up with an idea. One to further character customization and to somewhat satisfy the need for a transmog system with out all the converting and so on. If you are interested, please read on...
I love to give my character individuality & a signiture look that best fits their personality that was associated with them upon their creation. And I know many other players love that too, whether for Roleplay or not. But often times in order to achieve a certain build or play style, equipment sets are needed. These sets each have their own distinct style, but their visual appearance don't necessarily appeal to everyone's taste.
Their is also the complaint I often hear from players wanting to have the visual style of a lower level racial motif armor piece on their higher level character without cripling their stats. Or liking the appearance of an armor piece of a certain style, but not so much the appearance of the other pieces, which is frustrating when wearing a set with a certain style and having some pieces of gear that do not visualy appeal to you.
Sometimes their is a costume you really like, but their's just that one piece of gear that is off to you.( I mean this for costumes that use in games motif styles like: shrouded armor, theives guild leathers, wood elf vanguard, etc...)
I'm sure that people would love mixing and matching motif style armor pieces with each other to look awesome without cripling their stats or play-style as much as I would. So I came up with a solution.
I call this feature:
Appearance save
How it would work:
#1.Obtain your favourite looking armor pieces.
Craft, buy, farm the gear pieces that you like the look of (whether a monster shoulder or helm, a crafted level 4 bosmer style hood, or any dyeable set that is associated with a certain style category.)
#2.Create your perfect look.
Basically equip all the gear pieces that you want to create your characters perfect visual appearance while disrigarding the functionality (set abilities and stats) of said gear pieces.
#3.Press the save appearance button in the collections menue under appearance.
#4.Open the new sub catagory (My outfits) and find your new look saved in an open slot.
#5.Equip your costume!
Now your outfit works like all the other costumes. You can wear any gear set you like but the saved outfit when selected will override the appearance of your current gear like costumes do now. You can dye your outfit like costumes can now. You can wear hats with your outfits and so on...
Now you can venture in tamriel looking exactly how you want to look, without worrying about ruining your stats.

I didn't include weaons because they can't be dyed and would make things much harder.
Hope this inspired some thoughts.
Fair well, for now…
