Does any one know if there was ever a mod that changed the Bloodmoon clothes to fit Better Bodies models? I really like the nordic red wool shirt but it looks bad compared with the reworked clothes from Vvardenfell.

I don't think there is. I tried looking several times and never found one.

Hmmm, I wonder why. Not worth the effort I suppose.

The robes added by Bloodmoon have been updated. They can be found http://canadianice.moddersrealm.com/RobeReplacer.html?action=downloads;sa=view;down=48, in the customizable Robe Replacer at the CanadianIce & Howndog forums.
You have to register to download, but it's worth it since they all look good.
