A breast lift can be performed with or without implants and with or without an internal bra(mesh). I recommend you seek out a properly trained plastic surgeon(likely a few) to get some opinions as to what would be best for you after a careful history and physical examination is performed. Often a lift and augmentation can be performed without the use of an "internal bra". The trent in plastic surgery towards using an internal bra/mesh is much more common in revision cases than in primary cases. Some surgeons feel the mesh can be used even in primary cases to assist in supporting the lift and will likely lead to longer lasting results. Again, seek 2-3 consultations with properly trained plastic surgeons, they will help you answer this answer.good luck
