Miss March 1972
Ellen Michaels

Another awesome presentation of the full-cup string-bikini tan line, made even more so by the Native American accessories, both on Ellen's body and in the background. Our only gripe with the body jewelry is that it blocks the view of her tan-lined nether region.

Miss August 1972
Linda Summers

Lovely Linda definitely has a rack that deserves to be set free and put on display as often as possible, but we're happy she decided to keep her bikini top on while sunbathing before this photo was taken. Her boobs wouldn't be nearly as eye-popping without the tan lines.

Miss September 1975
Mesina Miller

The eyes, the hat, the hair down there, the perfect body—there's a lot here to distract the viewer from the subjects at hand. Which, of course, are the tan lines. The strapless, cup-only configuration on top is definitely different. Down low, it's a wonder to behold.
