Class Criteria

Ladies

Ms. Bikini Shape Under and Over 35 

The Ms Bikini class is designed for female competitors who present a well-trained, athletic appearance without excessive muscularity, definition, or vascularity. Muscle size and conditioning should be visibly lower than what is rewarded in the Figure, or Physique classes. Competitors displaying muscularity more appropriate to those classes may be marked down. Along with the correct level of muscularity, Bikini athletes will be rewarded for an even balance of development throughout the body and an aesthetic overall shape.

Attire Requirements for Women’s Bikini Class:

Competitors must wear a two-piece bikini or posing suit. The top should fasten at the back (not with a crossover style). The bikini may be any colour or design, but the bottoms must provide sufficient coverage and must not expose the genitals or the gap between the buttocks. High-heeled shoes are required. Jewellery is permitted.

NAC UK - Standard Bikini Posing 

1 – Front Pose:

Athletes should face the judges with one hand on the hip and the other resting at their side, no higher than waist level. Long hair must be brushed aside to ensure the physique is fully visible.

2 – Quarter Turn to the Right:

Athletes will turn so that their left side faces the judges. The right hand should be placed on the hip, and the left hand should remain at the side, no higher than waist level. The left leg (closest to the judges) should be slightly bent with the heel raised, while the right leg remains straight with the heel flat on the stage. Athletes may turn their head to look at the judges. Hair must be brushed aside to avoid covering the physique.

3 – Rear Pose:

Athletes will face away from the judges with one hand on the hip and the other at their side, again no higher than waist level. Hair must be brushed aside to fully reveal the back and shoulder structure. No bending forwards is permitted.

4 – Quarter Turn to the Right:

Athletes will now have their right side facing the judges. The left hand should be placed on the hip, with the right hand at the side. The right leg (closest to the judges) should be slightly bent with the heel raised, and the left leg straight with the heel flat on the stage. Athletes may turn to look at the judges, and hair must be kept clear of the physique.
