@Arkngt: Was to positive about it. The only thing I got was an epic fail...well it worked, but seriously it was awful. Clipping is better looking ;D
OK, many thanks for giving it a shot.

Does anyone have an idea why Vilja won't equip this armor? I thought it might be because it isn't specifically set up for female chars - but changing that didn't help. Can't see anything else that is different from the modded armors she does equip. Might be a question for the Vilja thread rather - or it might be companions in general. No idea.
