I just stopped breastfeeding last month and my breasts are really soft and saggy like an old ladys skin! Help?

I stopped breastfeeding and now my breasts have stopped producing milk, but the skin feels really soft, very loose, and I was wondering will they thighten a little after a while or is this going to be permanent??? I know it is due to the streching they just went through, but I don't like the softness, it makes me feel like an old lady! Will it go away???? Is there anythig I can due to make them less loose???? Mommy's advice!??! Please no stupid comments this is very important!
