It is rude and arrogant for anyone to suggest that modesty has anything whatsoever to do with negative body image. Personally I think my body is fairly terrific -- but being forced to parade around nude to satisfy someone else's idea of what is correct? Not going to happen.
I would tend to agree with Pam. I know that part of my modesty is how I was raised as a child. It was not religious upbringing but simply parents who grew up prior to the 1940's when still alot of Chinese women in China, did not show much skin unless they were Westernized.

So my parents carried over the same old fashioned standard when they immigrated to Canada in the 1950's.

I have a good body image that since I am aware many women in my age bracket probably envy me ..based on their comments to me. And cycling often has helped me alot in weight control.

But still, the most skin I even show are my legs in shorts. I don't even wear cropped tank tops...because I'm small up top.

So maybe I don't feel totally la-de-dah butt naked in a women's change/shower area...because I'm small busted... a hang over from teen years.

Ach,.....I haven't seen my sisters totally naked as a adults, except when they were babies and helped my mother by taking their baths, as the eldest kid. We're very polite to each other....we turn away from each other to change. But don't worry, doctor sister will smarten us up if she needs to examine us.
