Orb,
I can honestly say when someone does every now and again notice, and remember, I wear a 38DD/DDD bra, I can't hide, only camouflage, just look at my avatar, it's 99.9% women and they either ignore me like they would any other woman, if you have seen one breast, you've seen them all, or give that acknowledging smile of understanding. I don't really pay that much attention any more to my chest. My attention is not drawn to it since nothing is moving or jiggling or bouncing thanks to my bra. And that's the same reason no one else pays any attention either. No reason to look. I mentioned that fact to my doctor and she said that she experiences the same thing. That's normal. Once I realized that and saw it in real life, I stopped worrying what others thought.
