I don't think it's prudishness, I think it's more like embarrassment and comfort. At least, comfort is my guess for the granny panties part. I don't wear those.

I do cover up a lot as a way to hide my body. It helps to alleviate dysphoria. And I get the impression that there are a lot of other transfems here as well. Maybe there are cis girls here that cover up because they are unhappy with their appearance as well.

And actually this is most of a "place where the cool unstable bitches who society hates due to their instability" hang out

jealous of some women sometimes

That one I could’ve ticked, but it said other women.

And hiding ones body is about insecurities I guess. It also can be really hot in summer

Me! ;)
