In my younger days, during puberty any beyond, I lived at a marina in Northern Ontario where I played the role of a Tom-Boy. No bras for me, I didn't even want breasts. My mom encouraged me to wear a bra but I resited where and when I could get away with it. Besides, those things were a pain in the butt. When I went to school I was teased constantly when I wore a bra, and the guys would snap the back every chance they could get. That made me hate the things even more.
You may have a point on that ligament thing. I never had saggies until well into my thirties since I spent most of the time out of a bra. Of course, during the work day I would wear one unless I had sufficient cover to avoid distracted males (in my job it's counterproductive for people to be distracted, I teach college engineering). Once I get home it's back to the comfort of free breasts.
Since my breasts were oversized to begin with, having children pushed me over the edge once lactation ended (pencil test failure). Thanks to you gals (and guys) I feel less ashamed of my "natural" saggy look. Brian still loves to look at firmer breasts, but I love him for it.
What do we do to get this thing going? I'd love to be able to go bra-less any time without distracting my testosterone-saturated young male students. Should I simply de-sensitize them by exposing as much as possible by wearing thin garments? Maybe they would come to class more regularly? I don't know. Any thoughts gals?
