Are bikinis immodest?

This was an interesting video.  I remember something from a sociology class, or maybe somewhere else, I just don't remember where, about objectification of women.  It's fascinating that when men are showed pictures of women in bikinis, they are more likely to view them as objects than as persons, as compared to women in modest bathing suits.  I'd like to find this guy's article on the subject...

The youtube page had a link to a site on chastity, called (coincidentally) http://www.chastity.com/
