Land's End has a new site called The Island where you can 'virtually' go and submit all your size info and try on various slimming bathing suits. They help you select the best bathing suits based on your body shape.

You can submit all your key measurements (height, weight, bust size, rib cage, waist, hips, thigh, inseam and torso) and then see how the various bathing suits will look on you.
