I only have one headlight and I have not worn a bra since I was diagnosed 2.5yrs ago. I always loathed bras anyway. I usually wear a cotton top of shirt material when out and with pockets on the front which kind of hides the missing one and the nipple of the other.
The other day I was giving out how to vote cards with my shirt on and then a tshirt with the vote logo on it over the top. Well the temperature climbed to 33c and then I got hot flushes every half hour so I had to take the shirt off and just wear the clingy T. The logo sort of skewed to one side over the missing boob but I tell you, in over a thousand people who passed me, not one stared at my chest and not one commented either. People don't really care so I don't either. Of course I am prepared to talk about my bc journey if someone asks. Bra free and loving it!
