FAQ
Reader questions
Are 2025 SI Swimsuit styles suitable for competitive swimming?
Most 2025 SI Swimsuit styles prioritize fashion and comfort over competition-level hydrodynamics. Choose minimal seams, bonded hems, and firm-control fabrics for light pool use, but verify chlorine resistance before frequent lap swimming.
How does the sizing compare to previous years?
Brands refined measurements in 2025, with more consistent waist and hip grading across sizes. True-to-size ordering is recommended, and many labels provide detailed fit guides per style rather than relying on generic sizing.
What is the best way to care for recycled fabrics?
Rinse suits in cool water after each use, hand wash or use a gentle machine cycle, and air dry away from direct sunlight. Avoid bleach and fabric softeners to preserve elasticity and colorfastness over time.
Can I mix pieces from different 2025 collections?
Yes, mix-and-match sets and modular designs are encouraged. Coordinate colors within the same tonal family and balance structured tops with relaxed bottoms for a cohesive, intentional look.
