Elrond doesn't have as many outfits as his daughter has. Nowhere
even near that!
Nevertheless, it is quite complicated to get an overview and to
distinguish one outfit from the other. It's all still quite clear
in FotR, but in Two Towers, it becomes a mystery. He's mixing all
kinds of robes, drapes, sashes, mantles...plus, there are some pieces
that have been cut out, apparently, when the Arwen scenes had to
go - like the Arch outfit for example. It's all a huge guesswork
and I don't claim that my results are final :-)
that are already researched have an icon next to them, all the others
have just a picture when you click on them.
