Legs and hips are indications of beauty while breasts in our culture are indications of sexual beauty as well as regular beauty. Being caught checking out a girl's shape equates mote as a "Hey I find you attractive" sort of statement, while being caught staring at a woman's cleavage is closer to, "I'd totally be jacking off to you right now if I could."
EDIT:
Also your example isn't a double standard. The likely situation is that you're not very good looking, while the football players probably are better looking. They're certainly more dominant and in better shape, she's just appealing to the better mates.
I mean, who are you going to be more careful about offending, the guy you want to bang or the guy you don't want to bang?
This a bit.
Are you seriously moaning you cant oogle tits IRL?
Some guy you dont know with his eyes down your shirt is usually not a pleasant experience, because the guys who dont see the need to be subtle about it are most commonly the same kind of guys who dont see the need for other things... like soap.
Women are like this about tits because when you are a woman the message is `You are your tits! Tits are great, but dont show them off or you are a whore!`. Its perceieved as pretty much a purely sexual area of your body, unlike legs.
It gets a bit annoying.
And with things like articles on here that has more to do with wider issues of treatment of women by the game industry which is a whole other conversation. And as for why characters like Ivy are an issue, its not because of their sexualisation but because thats basically all there is to them. Moviebob did a good show on that, I suggest looking at it.
Basically.. deal with it. You're a guy. You dont have people leering at you, and if you want someone to leer at, type tits into google.
