I think there are some genetic factors involved as well. In my extensive scientific research of the physical aspects of the female body (i.e. looking at lots of pictures of naked chicks) I have made some interesting observations. Particularly, with regard to small-breasted women.
I have seen numerous examples of B-cup-sized breasts that are perky and firm and show almost no sign of sagging (Hey, watch where you point those things! You could put somebody’s eye out!) These breasts usually belong to a woman between the ages of 18 and, say, 23. Every now and then, though, I’ll see a photo of a woman who, by all appearances also falls into the 18-23 age group, and who also is blessed with B-cup breasts. And yet, her little boobies are obviously sagging, sometimes excessively so.
I think there are a number of possibilities:
1 - pure genetics: some women’s skin is simply more elastic than other’s
2 - even small breasts can sag a lot is the woman is not in the habit of wearing a bra
3 - hi Opal
4 - weight loss: a woman who is overweight and is able to shed most of that weight may lose a lot of fat from her breasts; her breasts are now smaller, but they retain the extra skin from when they were larger and so appear to sag
5 - physical activity: an active, athletic woman may be more prone to sagging, simply due to “bouncing” when active
