I will get the ball rolling.
I generally consider myself to be a modest dresser. I am fairly curvy, but I generally avoid showing cleavage and also avoid short skirts and very body-conscious attire and the like.
Not only do I find that with my curves that this may not be the most flattering way to dress my body, but it also doesn't express my personality or fit any of the stations in life I have held yet.
Despite being curvy I don't really have many hang ups about my body. I am comfortable in a bikini, so I don't feel that my modest preferences come from this.
I might be less-than-modest in some other areas though. While no one appreciates having to look at a constant display of situation-inappropriate boobage (whether purposeful or accidental), I am much less worried about slips and accidents of the potentially exposing kind.
For example, while I don't wear truly low-cut tops, I am generally still comfortable buying and wearing a shirt that might potentially provide and eyeful of cleavage and maybe the edge of a bra when leaning and bending if we both happened to be positioned just right. Unfortunately, because I am chesty and look best with a slightly open neckline and a looser fit-- this happens. However, it doesn't really bother me. I wear fuller-coverage t-shirt bras and really see the exposure as no more than I would get if I was wearing something showing cleavage or that bikini.
While I don't go around purposely flashing people (especially at church/work, ect), I do expect the people I am around to have a modicum of decency and choose not to stare down my shirt and be excited or bothered by it when there are clearly other options. After all, there are very few people out their that have never seen a woman's body/boobs before. Most of them have mothers, and therefore not everything has to be over-sexualized out of context.
In more casual situations, you won't find me in short shorts and a tank top, but I also have no qualms about whipping off my t-shirt to shake out the grass clippings or ants in it when I am wearing a sports bra and am out with friends or family in a situation where males in the group felt comfortable going or working shirtless.
Of course, my general feelings about these things could have come from growing up in a fairly open family where nudity or semi-nudity is still common (even in a househould of all-adults of different generations and sexes) where nudity in the home or out on the ranch was not sexualized.
It also might be a reaction to a bad experience where I dated a man from a fairly strict religious sect. that preached that the way a female dressed was responsible for the actions and impure impulses of males. I still insist that while women can portray themselves as sexual objects, women are not at fault for other's perviness and bad behavior.
I appreciate the beauty in all kinds of bodies, yet I tend to dislike how sexualized our society has become.
