A big part of Marilyn's attractiveness is in the way she moves. Have you seen any of her films?
If not, watch one of them. Just watch... the way she moves. She just flows, effortlessly, through space. It's like her muscles don't even need to have concentric contractions. Even the way she does nonchalant things like sitting down on a couch. It's just all so... lithe. So smooth and perfectly feminine.
So goals, for an awkward spaz chick like me. So goals.
She was extremely good looking, but much of her excitement could never be captured in still pictures. She represented both physical "hotness" and a sensuousness that can only be hinted at in photos. The way she moved. The way she spoke. The expressions she would take on.
If you did not live then, it would be close to impossible to see now, even in her movies, just how much she was able to excite America, even the world. She was nowhere near "basic". She was an icon of "sexuality".
