I hate bras too. Never had one that was comfortable. I wore them to work while I was still able to work, and I still wear them when I occasionally run errands or visit a relatives home, but around my home and yard I go braless. I live alone, and rarely go out in the yard when there are a lot of neighbors around. Some years ago I had a dog that had to be walked, as the homes we lived in while he was alive didn't have a fenced in yard. I don't recall ever wearing a bra while walking him, but I am a nite owl, so I often walked him at weird hours. I am big out front, so I do have to wear bras when going on errands, but I don't go out much, so if I want to go braless at home, that's my business. Anyway, bras are very uncomfortable, and are hard to get a good fit. They also tend to ride up, which makes them even more uncomfortable, so if you can get away with not wearing them, and don't want to, then it's your choice.
