The "Bay Watch" bikini life jacket concept is brilliant on three levels: It can help save lives, it is much more attractive to wear than traditional life jackets and your likelihood of being saved by a male lifeguard in the area probably increases ten-fold when you are wearing it. Plus, it looks as though there is some additional padding in the rear to achieve J-Lo levels of buoyancy. Again, it is only a concept at this point, but it certainly has mounds of potential.

I remember from some swift water search and rescue classes that women naturally have higher rate of survival compared to males. Boobs aren't always a bane. They increase the probability that a person will float chest side up.
There is a major flaw in this design, aside from being silly. If one really wanted to improve survivability, one would have the front of the bikini bottom inflate, not the bottom.
This just going to pop off leaving the wearer naked, with out a flotation device. Better wear the unfashionable PFD.
