8-Line/Hourglass: The 8-line can go all ways with swimwear. In terms of designs and silhouettes almost anything is possible. Try picking high-cut bottoms or swimsuits and solid colors. Decorative details such as bows are fine, but stay away from over-the-top accents. Pick slim-cut items to accent your pretty waist.
O-Line/Apple: Pick bottoms or swimsuits with a French-cut leg: high-cut to emphasize the slender legs which causes a totally slimming look. And try a straight neckline, wide shoulder straps and padded underwired cups. Do you prefer a swimsuit? Then pick one with slimming features. Are you a fuller apple? Opt for a swimsuit or bottoms, team with a skirt and put the accent on the neckline with some eye-catching details.
