@Bard2dbone - Penelope was the only one I could think of off the top of my head because having a fat heroine is so firkin rare that I could not immediately dredge up other examples.
And since we're on about personal wardrobe choices... We don't really know that she has much choice in the matter. I've seen the options for plus-sized ladies and it's pretty much "sack" or "shapewear". Earth Mother or Mae West. Those are your choices. Her choice of Manic Pixie Pastel Geek is simultaneously mould-breaking and adhering to the aggressively feminine.
But you are totally correct about fat people in media being removed from sexuality. Fat people are allowed to exist, sure, but they aren't allowed to have sex scenes or a consistent romantic relationship. That would be "glorifying obesity" 9_9
To be fat in the Media is to either be Polished to Perfection or the Token Slob. It's not real, but it influences so many people who are also heavy. They can't be seen in comfortable clothes or they'll be mocked as a fat slob. They have to dress up in order to be accepted as human.
I could go on about this. At length. If I have time, I might pop over to my Wordpress and do some opinion pieces.
