Also freedom-boobed here! I stopped wearing one in 1998, started again for a while when pg with ds4, and have worn camis since. I get very cold if I don't wear a cami, especially because they keep me covered up while I nurse. :)
I was a 36DD when I wore a bra, and being on my fifth nursling, my breasts are healthy, firmer and perkier than ever before! I'm also much, much smaller than when I wore bras. I stopped wearing a bra when I developed breast-concentrated cancer. So, I quit the bra, th solvent-based art supplies, isopropyl alcohol, processed and/or packaged food, all "beauty" products, and in four months with lots of sleep and fresh air, my free breasts were tumour-free, and I have had no further incidence.
Recently, a friend asked me about giving my girl-child her first bra, and I said, "What are you, crazy??!!! Why would I ever do that?" Then there was a long, weird, stunned silence, so I added, "Well if she wants one, I'll get one for her, but you'll never hear me encouraging anyone to wear a harness." Then with incredulity, "But you, wear one; why wouldn't you let her, too?" My surprised response was, "I don't wear a bra. I haven't for 13 years minus a few months." Then it occurred to me that in all of the time we've spent together, they had no idea that my boobs have been free! They've not noticed or deliberately observed my breasts; how awesome is that?! :)
