Hmm.. I would love to be an "8" but that's not certain, it's more of the idea of being a single digit..
I honestly don' tknow what is my personal "perfect" size since I've never been thin like that, and I'm the tiniest I've ever been..
For my particular ideal body.. I would say Scarlett Johansson~ While I admire toned and fit women, I love Scarlett Johansson b/c she is at a healthy, curvy weight, still thin (not Hollywood thin). I think she has a very feminine/soft figure and she's 5' 4" too.. I love her size and body type!

I love the picture next to Natalie b/c while I love Natalie Portman, Scarlett looks so much more womanly/feminine in both pictures.
