Buying Guide: Key Purchase Considerations
- Fabric composition: Look for 80% polyamide and 20% elastane for a balance of durability and stretch. Higher elastane can improve recovery but may wear differently with chlorine exposure.
- Intended use: Choose higher compression and thicker lining for tummy control or full back coverage for modesty during water activities.
- Care and durability: Repeated washing should preserve color and elasticity. Follow care labels to extend fabric life.
- Fit and sizing: Elasticity varies by brand. Consider size up for a more comfortable fit in high-mobility pieces like bikinis with adjustable straps.
- Coverage preference: Top and bottom cuts range from full coverage to cheeky. Align with personal comfort and activity level.
- Care for color and texture: Some fabrics maintain color after sun exposure; others may fade with chlorine or sand abrasion. Prioritize fabrics with proven colorfastness for outdoor use.
