Re: How important is it to wear a bra?
I’m not sure but after the age of 25 skin starts to change/mature so I guess if you start to take care of your body you can avoid the sagging.
When it comes to women who have gone through pregnancy and breastfeeding and who are even quite young the problem can and does occur and you do need firming lotions. You won’t notice the sagging until you stop breastfeeding.
