Seriously people, they are just boobs. If guys come to the game without shirts, girls can come to the game without shirts. They are just boobs. Matter of fact, in jurisdictions across the country, women can go topless. It is not a big deal.
People that have an issue with this, are the same people that refuse to discuss sex with their kids and then their wonder why their kid gets pregnant.

Just a matter of courtesy. If you want to hang out with your wang out around your kids, whatever. It's still bad form to do it in public generally. Certainly women going topless is less of a faux pas, but in the US it's still mostly considered rude for women to go topless in areas that aren't designated as topless, and even more so if it's in an area with kids. Even in places where topless beaches are common, you still generally see women wearing tops around town.

ETA: Obviously I personally rebel at society's unreasonable strictures on women and encourage them to free the tatas whenever and wherever, provided the women in question are reasonably attractive.
