Wow, how young are you? The only women whose breast do not sag a little are very young women and skinny models, even some models with A cups have saggy breast. Her breast are not sagging that badly, but it is in poor taste to not wear a bra and have your nipples sticking out like that. However, I don’t mind and they are, after all, her breast. Don’t want to see them, don’t look!
I think that’s just an optical illusion...you know, they follow you around the room...
That's because you've been looking at them upside-down.
They all look the same upside-down.
