Its an issue for the BF mother and no one else.
Its not for any other person to look at another and try and work out why they are doing something.
Having a neck high scarf on, for me, was simply easier to manouvre underneath with plenty of room and giving baby plenty of air and space too.
It was nothing - nothing to do with wanting to be hidden from the neck down like a Victorian bather.
My cover was in valuable to me, when I got the hang of BF with more ease, I was able to graduate onto tops, and scarfs.
I never bare my breasts on a beach, and whether anyone likes it or not they are sexual objects.
Men get turned on by breasts.
You can ban the sun but they will still find them sexy.
I chose to cover mine when BF because I always cover them. I do not even wear tops showing much cleavage.
They have never ever been something I want to show off, or a feature.
