Breast Development

I'm 17 and I'm wondering if my breasts will ever even out. I know it's common for women to have slightly different sized breasts. Mine are noticeably different. The bigger 1 sags more and is less perky. It also has an areola much bigger than other breast, maybe twice the size. The smaller 1 is more perky. I'm not overweight or anything. The size is not like a whole cup difference, but it's still significant. Can my breasts even out & come close to the same size & will my areola get any bigger?
