I know that Elisha Cuthbert used a body double /stunt in GIRL NEXT DOOR. But I must add Julia ROberts and Sandra Bullock (excluding her performance in AMAZON) into this non nude list.

Jennifer Aniston was topless ( although in a dark scene) with Jake Gylenhall. Duff is still teenager and I must agree with answe on ALBA and Mandy Moore.

Hillary Duff. I am sure many other actresses would also refuse, but they would not tell everyone they would refuse to, because that could cause them to be type cast as a woman who is not sexy and that would limit the number of parts she would be considered for. I have been a fan of Ms Cuthbert since she was in popular mechanics for kids, but I have no desire to see her butt crack, so it doesn't matter to me if it was someone else's body.
Rumor has it that Hillary Duff's breasts are small and 1 is smaller than the other, I guess that is why she does not want to show them to us.
Mandy Moore showed us the side of 1 tit in "how to deal", Perhaps she is glad that nobody watched that movie.
