Did anyone make a resource with hanging clothing? Whether robes, shirts or pants, hanging from a hook, coat-rack, closet corner or laundry line?

This would be a large undertaking. Each article of clothing has a "on the shelf" look when you take it, basically folded somehow. This instead would need to be replaced with graphics for each clothing item showing it hanging. Then a script would be needed to choose the correct graphic depending on what your doing. Then you might want some physics to the robes and clothes.

If this search proves unsuccessful, may I suggest the House of Mannequins mod. You can buy different styles of mannequins and put them in your house. One of them is invisible or wraith like. When clothes are on this one, it kind of looks like they are hanging.

I believe DonnerGott was asking only for models of clothes attached to hooks or ropes, i.e. only as statics that would add some atmosphere.

Korana did this -- you might want to search her on http://morrowind.nexusmods.com/mods/27167/? also try Morrowash - sadly I think that was part of ElricM;s site

Edit: So I'm certain I have a mod somewhere of clutter from Korana that has some clothes on a washing line - unfortunately my PC is off at the PC version of ER trying to get rescuitated so I can't check for you - Morrowash might have had clothes set up as hanging items as well - they would likely be flat meshes - I don't recall any clothes hangers but I do recollect pegs and washing lines
