I stopped wearing a bra while in my last month of pregnancy with my baby who was born this past September.
I'm at least a 36/38 E/F and I'm starting to get used to how it looks. Right now, I'm nursing tons and just wear stretchy tanks.
I finally remembered to search this thread here because of the little FaceBook meme that's going around right now - women are posting just a color as their status update, and it's supposed to be the color of the bra that they're wearing. Some versions of the meme say that it's to raise breast cancer awareness. After reading this thread, I'm tempted to post a link that talks about how wearing bras can adversely affect a woman's health
I actually was surprised at how many of my FB friends admitted to being braless at the moment, and how much more comfy it was. I saw that sentiment echoed in the responses too. When I shared with these girl friends that I haven't worn a bra in months, they were jealous that I'm so "free." It's sort of nice being officially braless!
