Yes, why not!! And leaving this argument aside breasts are exploited in so many way it would be ridiculous hypocrisy to say otherwise. I wouldn’t even make the proviso that it has to be dignified, or course try to make some comfortable provisions for it, but it’s not as if it’s a flaunting or sexual thing and a glimpse of a milk engorged boob isn’t going to hurt anyone. Isn’t this allowed anyway?
