It's the ultimate supermodel yearbook. Join the four photographers whose work was featured in the 2011 Sports Illustrated Swimsuit Issue on a behind-the-scenes account of their travels, revisiting their experiences through never-before-seen images and exclusive commentary. In this large-format, 176-page collection, Swimsuit Portfolio: Fantasy Islands showcases 17 of the world's most exquisite bodies at four exotic beach locations-Turtle Island in Fiji, Sentosa Island in Singapore, Peter Island in the British Virgin Islands and Boracay Island in the Philippines. Grab your passport and take the tour with Brooklyn Decker, Irina Shayk, Hilary Rhoda, Esti Ginzburg and Christine Teigen (among others) as your guides. With dozens of previously unpublished swimsuit shots, it's an expanded look at the making of the magazine's best-selling issue.
