Let me preface this by saying I am a man, and smoked a little too much, so I’m sitting here thinking… what is or was the original purpose of a bra? Weight support? Vanity? Covering the nips so people’s eyes met your eyes and you can have a normal conversation? Like what’s it all about?
I have never needed one for support, but for the past 20, 30 years the US has had some sort of weird rule that only smooth lumps are professional, no hint of actual breast shape. That’s easing in non-professional public life, finally, so I don’t wear one a lot of the time, but at work wear something with light padding to make that weird Barbie doll lump shape.
Sports bra for running, yes that serves a practical function - holds the boobs still so they don’t bounce and hurt. So if one is more endowed and bouncing in everyday life, I imagine that a bra with structural support would be more comfortable than nothing.
I really wanted to answer that the point is right at the front of each cup!
