i would definitely never, ever call blake lively prettier than amber. amber's features are very soft and malleable to different ideas/looks whilst blake..well. this is the amber thread so i'll hush
you're right though, i think sensual is the best word. regardless of what she does, the way she carries herself exudes a sexiness which can be both good and bad depending on what roles/looks you're going for. (ie, her guess ads were perfect but when paired with another, softer line she may not fit)
