If it didn't grow hair while I was bursting with T, it won't now for sure.
The reason hair appear at menopause is because E levels go down while T levels stay stable, that's the same reason women gain weight around the abdomen.
So, if you would have been hairy if born a male because of genetic background, you will have hair sprouting at menopause. But, if you had few hair as a male, why would you get more hair with less T than you had before.
As for sagging, a lot of this has to do with weight gains/decreases with increases/decreases the size of the breasts considerably (band size and C cup goes up a lot, so the breast weight increases a lot) and taxes the skin, which due to sun damage may not be up to it. This, coupled with involution (gland size decreases as E level decreases, reducing the inner structural of the breast), leads to sagging breasts in many women. Some people also have much better skin tone than others, some women sag at 20 with small breasts; a girl I knew was a C cup and she was 35 and had very little sagging.
If you've got 36B, don't take much sun and had little sagging at 30 (17 years past puberty), there is a good chance you won't have a lot of sagging by the time you hit 45, especially if E intake is kept at a good relacement level and your weight is stable.
Also, remember that for someone like me who's got her breast at close to 40, there's a good chance that I'll get breasts that don't sag to much at 60!!! YAY.
