I have strapped my modest girls into push-up bras for years...after having lost 180lbs, they were deflated and limp like I'd breastfed a dozen babies, and low, because I have a lot of stretch marks forward of my armpits. At the age of 24, that was less than ideal. Now, whatever. I have noticed, though, that since starting eating primally they have filled out a bit, which I don't mind...they'll never be any higher than they are unless I have them lifted but, since they're only a full B cup anyway, there isn't much point.
My mister has mentioned for years he doesn't understand why I don't go braless more, having dated a girl before me that went without all the time. His mom goes without also having been through breast cancer many years ago although she's never alluded to thinking bras have something to do with breast cancer. She just says she's more comfortable without.
I am getting into the habit of taking my bra off when I get home for the day, but I honestly just don't think about it most times as my bras are so comfortable. That said, this thread has prompted me to look into other, less restrictive options that'll also work for (some of) my day-to-day...that said, I don't think I'll give up wearing a proper bra for work-related stuff. Nipple-age isn't an issue for me, quite the opposite...I have one that's completely inverted and one that's flat, though it will come out for a look around once in a while, without rhyme or reason (not temp-related).
Has anyone tried Coobie bras (shopcoobie.com)? I saw an ad in a fitness mag and checked out the website...at $20-22 a crack (although I do have a coupon code), they're a little steep in comparison to some others out there, but if they're as ah-mazing as the reviews claim, it might be worth it.
