CEPHALOPOD MOD: A day at the beach only asks you to show in a swimsuit, but a night at an aquarium demands something a touch dressier. We got to thinking about Night Dive at the Aquarium of the Pacific, and how one might go about getting fancier while keeping the waves close. Something like this Octopus Necklace from Accentuality just might do. 18K GOLD-PLATED PRETTY: It's $58. Figure under eight bucks a tentacle.
