I'll try to go from earliest to latest in terms of time period the best I can.
First off, we have the Persian robe!http://www.payvand.com/news/07/mar/Achemenid-Persian-officers.jpg
I'd like a robe like that. Black with dark red trim though.
Secondly, I would like a long velvet cloak in either black or a dark purple.
In general I'd wear a lot of these designs: http://www.sharpe-designs.com/dragonesq
All four pages are full of goodies
I'd also go for a long velvet coat as well as leather pants.
