I have to say, @bluebehir, that all of your arguments simply say, “I don’t see it so it must not exist.” This is what feminism fights against. Just because you think that pictures of women with cleavage aren’t sexualized doesn’t mean that they don’t appear that way to others. You even continue to talk about your teacher that elicited excitement when she leaned over in her low-cut shirts!
Please consider that we are discussing something that may only have a pleasant or neutral effect on you, but may have a negative effect on others, in terms of body-shaming and misleading models of beauty. Please, reconsider what you might say if your daughter dressed like Atlanta AND looked like her, too.
