to answer the question.. the last pic has the the best form (both the bow and dampeners) hands down.. the first looks like the bottom of the bow is not deep enough in the chicks shorts..
saline filled breast implantsSaline-filled breast implants were first manufactured in France in 1964, introduced by Arion[25] with the goal of being surgically placed via smaller incisions. Current saline devices are manufactured with thicker, room temperature vulcanized (RTV) shells than earlier generations of devices. These shells are made of a silicone elastomer and the implants are filled with salt water (saline) after the implant is placed in the body. Since the implants are empty when they are surgically inserted, the scar is smaller than is necessary for silicone gel breast implants (which are filled with silicone before the surgery is performed). A single manufacturer (Poly Implant Prosthesis, France) produced a model of pre-filled saline implants which has been reported to have higher failure rates in vivo.[26]
Saline-filled implants were most common implant used in the United States during the 1990s due to restrictions that existed on silicone implants, but were rarely used in other countries. Good to excellent results may be obtained, but as compared to silicone gel implants, saline implants are more likely to cause cosmetic problems such as rippling, wrinkling, and to be noticeable to the eye or the touch. Particularly for women with very little breast tissue, or for post-mastectomy breast reconstruction, silicone gel implants are considered as superior. In patients with more breast tissue in whom submuscular implant placement is used, saline implants can look very similar to silicone gel
(In medicine, saline (also saline solution) is a general term referring to a sterile solution of sodium chloride (NaCl, more commonly known as salt) in water but is only sterile when it is placed intravenously, otherwise, a saline solution is a salt water solution. The sterile solution is typically used for intravenous infusion, rinsing contact lenses, nasal irrigation, and often used to clean a new piercing. Saline solutions are available in various formulations for different purposes. Salines are also used in cell biology, molecular biology, and biochemistry experiments.)
