Re: Women 'showing' their bras / straps ... it has become a fashion thing. Models and 'famous' women - incl actresses are wearing clothes that show their bras and straps - and often their breasts. It's quite like the new torn T-shirts and ripped jeans they buy. Go figure.
And with all the gender confusion these days (e.g., men claiming to be women) it might also be a way for the females to outwardly proclaim themselves as female.
Problem for us guys (or, I should say, one of the problems we face) is that almost all of us with gynecomastia are obviously male, so 'presenting' a female attribute (developed breasts) openly is ... challenging. Some of us have experienced things like Ben - and others here - have shared. All of us have experienced at least some kind of discomfiture with our condition, and many have expressed the wish (hope?) that 'everyone else' would just accept us how we are.
As many here have come to realize, that may never happen - so we just press on, coming to the conclusion that we will not be shamed by it. That probably does not mean that we will prance around in public openly displaying show-off lace bras (like those sold at Costco for example), or flaunting our bras / breasts the way women do (and, in a way, are expected to !).
But I think it's ok for us to be seen as 'developed', and also as wearing bras for support like women do...I think we're slowly getting there in society.
I've come to realize that I am more comfortable with my breast development than others might be, and I've also noticed (as have others here) that most of the time 'others' don't even notice, and when they do they don't seem to care anywhere near as much as I do.
Apologies for the long post - but had to 'get it off my chest' (LOL).
