during bake easy way of turning render OFF on other objects??

I have a scene/model with a number of objects (its a dancer and a whole set of clothes) while i am doing a texture bake is there a way to turn render on everything else OFF?? (so for example when im doing the bake for the dancer none of the clothes are even considered in the render). My problem is everything covered by another object lands up not being rendered.
