Origins: Mod conflict with Improved Atmosphere

Improved Atmosphere can be like blood magic sometimes.  It does certain things well, but usually at the cost something else you like.  I installed the Armor of the Devout mod and like the way it looks on Leliana.  When I took the team to the Brecilian Forest, I tried various options to spice up the way things look there.  Ultimately, I tried Improved Atmosphere.  When I went back to party camp, Leli's Devout Armor was transformed into something else with a vest over blue-sleeved shirt.  I tried de=installing then re-installing Armor of the Devout an the same strange outfit remained. 

Is there any file I can delete from IA to restore Devout armor?  I'd prefer not to delete IA completely.
