If you decide to get the implants DON'T skip the breast lifting part. I thought I'd "save money" and just have implants minus the lift thinking the implants would just fill in the loose skin and everything would be perky and back to normal. They look ridiculous and I have what I refer to as a shelf. The implants were put behind the muscle so if I would have had tight (not sagging) skin it would have probably turned out nice and firm but because I had saggy skin on the outside of the muscle it just looks like skin hanging off of a softball if that makes any sense at all. I can't think of any other way to try and give you a visual but trust me, don't skip the lift part!!
I had a breast lift and augmentation 2 years ago. It was for no other reaseon than for myself. My clothes didn't fit well, even bras were awkward. I'm very happy with my results. I picked the textured gel implant. Take at least 2 weeks off of work though. I only had 6 days recovery before returning to work and that was rough!! Good luck and take your time finding a good doc!!
You may be able to just have some implants put in to fill them out. Alot of the time even with a lift they put in implants to give you the size you want. Implants are between $4000.00 and $5000.00. A lift with implants are between $6500.00 and $7500.00.
