There's actually quite the debate going on right now on whether wearing a bra too much can cause sag or if wearing it too little can cause sag... Both proponents make sense though, breasts are not just adipose fat but muscle as well. I'd link to papers but I'll be honest it's a total clusterfuck full of contradictions. Additionally I'm a biochem student, not a medical one so I don't know which sources are more anatomically correct.
One thing we could do, the both of us, is look at how the sample size was collected for the studies if you like.
