Rose-pink tight-fitting sportswear showcases a perfect waist-to-hip ratio.

A young woman with a slender figure and graceful curves, with long, wavy dark hair, is taking a mirror selfie in a modern gym. She is wearing an eye-catching rose-pink sportswear set, including a tight sports bra and tight sports shorts, showcasing an excellent waist-to-hip ratio and fair skin tone. In terms of composition, she is standing sideways within the frame of a black Smith machine, holding her phone up with her right hand, stretching her left hand upward to grasp the top beam of the equipment, and lightly lifting her left leg, resting the line of her leg on the horizontal barbell. The environmental lighting is sufficient and even, presenting a cool industrial feel, with the surfaces of the metal equipment reflecting cold highlights, and the floor is a dark gray non-slip rubber mat with fine particles. In the background, clearly visible are arranged barbell plates, orange fitness equipment supports, and a white wall with black artistic lettering. The color scheme features a strong contrast between high-saturation rose pink and calm black and gray, supplemented by a few touches of orange. The overall image quality is delicate, with distinct layers of light and shadow, presenting a modern, fashionable, and vibrant fitness atmosphere.
