These are three outfits I made for my King Théoden minifigure that came with my Helm's Deep set.
About this creation
The main photo (above) is his normal everyday outfit.
This outfit is the outfit he uses during most of the battle of Helm's Deep.
This last one is the original outfit (he uses it at the end of the battle of Helm's Deep and most of the battle of Minis Terith).
Here is a link to see this creation on the LEGO Lord of the Rings gallery: King Théoden
You can also make these outfits if you have a red cape and a tan hair piece.
