Mid term idea!

My midterm time line will be all about what defines sex appeal. My fav artist is toulose lettec and I adore his posters for the moulin rogue. His image of sexy was found in prostitutes and the basic curves of a woman's body. Now In today's society we look towards advertisements in the media to form an opinion of what sex appeal is. Normally it's found in revealing clothes and naughty poses. But I want to build a timeline about bringing the ideas together and the overall idea of what define sexy?
