Yes, I know the 'right' answer is to want to look like myself but still:
Oddly enough, I absolutely love some of the clothes that Angela Lansbury wears as Jessica Fletcher. Some of them are so classy and expensive looking, and FIT: I love the idea of being able to wear classic, classy, "grown-up" pieces.
Body-wise, however, my miracle dream look would be Cote de Pablo, as seen as Ziva David. Now, short of a genuine miracle that would add 5" to my height, it's not going to happen but I love that compact, tight but feminine look.
