SIZING & FIT
Precision in Every Silhouette.
At Tefnut Swim, we view the body as a masterpiece of architecture. Our pieces are engineered with high-tension fabrics designed to provide a "second-skin" feel while maintaining structural support. To ensure your silhouette is perfectly framed, please consult our engineering measurements below.
THE MEASUREMENT GUIDE
All recommendations are in inches.

FIT NOTES FROM THE STUDIO
1. The Foundation Phase Fit
Our current collection is curated to provide a high-compression, editorial fit. If you are between sizes, we recommend sizing up for comfort or staying true to size for a high-impact, locked-in feel.
2. How to Measure
- Bust: Measure across the fullest part of your chest while wearing a non-padded bra.
- Waist: Measure around the narrowest part of your natural waistline.
- Hips: Measure around the widest part of your hips, ensuring the tape is level.
