Consumer Report's Magazine (Oct 2007) testers found that this deoderant "usually" did not leave any white marks as compared to the "Little Black Dress Approved" deoderants which tended to leave white marks fairly often (Dove left white marks on 9 out of 12 testers and Degree left white marks on 10 out of 12 testers). Right now I'm using Women's Degree Ultra Clear Little Black Dress Approved, and it leaves white marks on every color I wear, not just black. Argggghhhh. I'm buying Mitchum tomorrow.
