I have now got enough to show (38B), in particular my big pushy nipples.
I am gradually getting more daring (brazen?), as I find that nobody seems to take much notice!
In Summer, I wear often tee shirts which are tight enough to display my boob shapes and also the print of my bra straps, buckles and back band. Recently, I mistakenly wore a white bra under a white top and only when I got home after shopping did I see that my "lady harness" was quite visible from behind and that one of my bra straps had slipped off my shoulder.
I got absolutely no response in the supermarket queue. But then, who is going to say, "excuse me, sir, but you have lost a bra strap"?
