Question on the Cheerleaders Kit for Genesis 3 Female(s)

ThatGuy

Bought this item and tried it out (NOT on me, mind you) but the iray material setting for the pants, in white, seems weird.  There are "gray patches" on them that aren't there on the promo images.  I've turned down the reflective and glossy layered weight, thinking those might be the problem initially (perhaps picking up reflection fromt the "floor" that I have), but it's not. Anyone else bought this outfit and experiencing the same thing?
