And I think it's the type of clothes where you'd have to throw yourself back and feel very elegant and beautiful in."Rosario added: "Watching the show, I just felt myself sitting back more, and wanting to have better posture. There's something about it that just seems very striking and adult, which I really like."© Independent Television News Limited 2007. All rights reserved.
