For this Sunna Swimsuit cosplay outdoor shoot, a lot of thought went into the preliminary preparations. Since it was chosen to be by an outdoor Summer pool, sunlight and water reflections became the biggest variables. To capture Sunna's capable yet playful vibe from Zenless Zone Zero, the wig styling was specially treated with big waves, featuring silver-white twin-tails topped with a light green geometric hair accessory and a small black triangular clip on the bangs, instantly creating rich visual layering. In terms of makeup, to cope with the strong outdoor light, the base makeup used high-coverage and waterproof products, while the eye makeup and blush heavily leaned into pink tones to ensure an energetic look under the sun.
On the costume front, a black one-piece swimsuit served as the foundation, but to break the monotony of a large dark area, long knitted arm sleeves with pink-and-white stripes were intentionally paired. The arm sleeves actually gained some weight when wet and tended to slip down the arms, so hidden small clasps were added inside to secure them. That pink backpack along with the white wing props on both sides served as highlights of the entire styling; the wing material is quite light but fears water, so constant care was needed during shooting to avoid actually submerging them. The backpack itself also carried some weight, packed with touch-up supplies and counterweights to ensure it wouldn't get squashed when sitting down.
The temperature on the shooting day was very high, and the tiled pool ground was baked scorching hot. The first set of poses involved sitting by the edge of the pool with legs extended into the water; this posture was actually quite tricky to maintain balance for since the underwater surface was slippery, requiring constant core tightening to steady the body. The splashing water droplets were candidly captured by myself using a mineral water bottle from the side, trying several times to catch the most natural moment. To make the legs look longer, the photographer continuously adjusted camera angles, leveraging the wide-angle distortion of the pool water to stretch the image's sense of depth.
Later, switching to sitting cross-legged on a white lounge chair, or grabbing the backpack straps with both hands, the shoot had already been running for over an hour. My contact lenses felt somewhat dry from prolonged exposure to the sunlight, but my state unexpectedly relaxed. The posture in Photo 3 with both feet stepping on the mat and extending forward beautifully showcased leg lines, while the high-rise buildings and shimmering pool water in the background accentuated an overall urban vibe. In pose guidance, I tried to avoid overly rigid staging, attempting to channel Sunna's setting—calm when facing battle yet lively in private—manifesting it through eye focus and a slight torso tilt.
The hardest parts to handle in Swimsuit cosplay outdoor shoots are reflections and expression management. The lighting at 4 PM was slightly softer, and combined with a reflector board for fill light, facial shadows weren't too harsh. In post-processing, the true texture of the skin was preserved without excessive retouching, and the pool ripples and splashing droplets were handled quite vividly. Throughout the entire set, although my skin got a bit sunburned and red, seeing the light, shadow, and colors of the final photos made all the preliminary prep and scorching sun exposure completely worthwhile.
