Pin-ups are supposed to show how sexy women are (especially curvy women) so there is nothing bad about this post. Beeing "sexy" is nothing to feel bad about the sexist thinking would be to only see the woman as a "sex-symbol" and not for the person she is or what she can do. You can also see sexism in almost every little thing and ruin the actual meaning behind things...

People who are complaining that this is 'sexualising' women I think are getting confused between 'sexualising' and 'objectifying'. There is nothing wrong (in my opinion) with sexualising women (as long as they are an appropriate age obv), women are sexual beings, everyone pretty much is. OBJECTIFYING women is different. This means treating women and showing to be nothing more that objects for men's gratification, this post is not doing this. There are no men in the images, the images are of sexy, happy, confident looking women and shows their different styles and characters. The only issue I have with this is that the artist clearly felt that Ursula had to loose a lot of weight to be sexy enough to be a pin-up!
