Bikini contests consist of group comparisons and individual presentations. Two-piece suits and clear high-heeled shoes are worn for both parts. Suits can be of any color and may be decorated with crystals. Thong/T-back style suits are not permitted. Jewelry is allowed. Competitors must be over the age of 18 and cannot participate in any other categories at the same show.
Judging is based on having an overall healthy looking toned body with good symmetry, fullness, balance, shape and proportion with good posture, poise, confidence, and stage presence. Other factors that can affect overall appearance are suit fit, hair and make-up, skin tone, and complexion. Bikini competitors should not display deep muscle separation, muscle striations or an abundance of muscle size.
During the group comparisons portion, competitors in a class perform half turns as a group as directed by the head judge. A few variations of the rear pose are acceptable, however, judges may request a group to get into the same stance at times. Styles for the rear pose include leg positioning so feet are shoulder width apart or ankles crossed and with hands on the front thighs (competitors may arch their backs but leaning forward is not permitted). Another style is with one hand on a hip that is angled out to one side. See examples below. Competitors are also asked to walk a few steps toward the back of the stage and hold their back poses as a group. When directed to make a half turn and face the audience, competitors will hold their front poses as a group. The head judge will then direct the group to walk a few steps toward the front of the stage.
The individual presentation portion is a stage model walk. Competitors walk out to music to rear center stage and pause briefly in a stance of choice. Competitors then walk up to front center stage and perform half turns to show the front and back views of their physiques, then walk to one side of the stage and pause briefly in a stance of choice, then to the opposite side of the stage and pause briefly in a stance of choice, then to front center stage and pause briefly in a stance of choice before exiting. The individual presentation is not factored into placement scoring but does count toward consideration for Best Presentation awards when offered.
