And back to the original topic.
It's not a matter of liking thick vs. thin. There are many 'thick' women who look good - Christina Hendricks comes to mind. The model in the original post just looks out of shape to me.
However, the bigger thing to me is I just don't think she's all that pretty. There are pretty thick women and pretty thin women. I don't find the model pretty at all.
Oh, and if you like the 'UPS Girl' photo - umm, she's a porn star. Sandy Summers - look it up if you want. Don't ask me how I know that!
