Mercury Set

Serena Moon bikinis are designed to fit tighter and smaller than standard global sizes, especially for a sleek, sculpted look.

Please refer to the chart below and measure your bust, under bust, waist, and hips carefully before selecting your size.

1. Tailored for petite silhouettes
"Unlike most global brands designed for tall, model-like frames, Serena Moon offers a snug, form-hugging fit tailored for petite curves."

2. A tighter fit that flatters
"Our sizes run slightly smaller—on purpose. Because a bikini should enhance your natural shape, not swallow it."

3. Designed to stay up, not slide around
"Our bottoms are cut to sit higher on the hips, giving the illusion of longer legs and a more secure fit. That’s why our sizes feel tighter—but better."

4. Fit over formula
"Instead of following standard charts, we designed our fit based on real bodies and what truly looks best on them."
