Sailor Mars, Swimsuit, Sailor Moon

A woman with long black hair and bangs, dressed in a red swimsuit, posing by a pool. She is standing on the steps of the pool, holding onto the railing with her right hand, while her left arm is relaxed at her side. Her head is slightly tilted to the left, and she appears to be looking directly at the camera with a serious expression. The background of the image is out of focus, but it seems to be a pool area with blue water and possibly some lounge chairs or umbrellas nearby.
