How can I fix sagging breasts without surgery?

I have a rash on my skin that is caused by my saggy breasts. I don't care what my breasts look like, I just want to get rid of the rash. I looked into breast lifts but I am to old and poor (I live on a fixed income) for real plastic surgery. Can you just stitch the skin up? Or are there any other alternatives to surgery for sagging breasts?
