I have a stylish PFD/survival vest -- Modular Aircrew Vest. The attached pouches carry a couple flashlights, chemical lights, a marine hand-held VHF radio, a PLB and other good gear. Most importantly though, it will keep you breathing air.

IMO the new Switlik X-Back is plenty stylish and is supposedly very comfortable.
