Polymorph Outfit,  This spell allows you to change clothing.  The clothing of any one within  60' or the castor. The clothing do indeed get a saving through BUT  as the Person who clothing is targeted is not affected by the spell the person wearing the clothing does not save. The caster must focus on what the outfit will look like once it is changed. Zorcon used to like to make bostfull idiots in pubs, suddenly be wearing a diaper and a pacifier neckless. Or street preaching clerics wear jesters garb. 

Though he supposes that you could use it to change a knights armor into a chicken costume altering his AC.  

It is also quite handy for sneaking into places dressed as someone who belongs there. You know saves you knocking a guard over the head and dragging him into an Alley to steal his uniform I mean how barberic right? 

The Clothing will stay changed until  dispelled or forever cause sometimes the knight will decide he actually like the chicken costume..
