doutzen is more sweet/pretty/cute looking. I've never seen her as sexy.
Pretty much everything Adriana has done her whole career has been nothing but sexy so I agree with mdc.
adriana has dabbled in other areas but the bulk of her work has been sexy. That's why she's been such a popular sex symbol.
True I almost forgot how sexy Doutzen was in those Versace shows she used to do. VS seems to play up on her cuteness as she is always smiling in the pajama ads and rarely gets to do the sexier stuff.
My all time sexiest woman is Stephanie Seymour. She was sex on legs!
