SPORTS BRA DEVELOPMENT
Choose support from the intended activity and the complete bra construction—not from fabric composition alone.
Support level should reflect the target customer, body-size range, coverage, and the amount of movement the garment needs to control. The approved construction and wear-test results should support any low-, medium-, or high-impact claim.
Low-impact support
Commonly used for yoga, Pilates, stretching, and everyday studio wear.
Medium-impact support
May suit strength training, cycling, hiking, and general gym activity.
High-impact support
Typically developed for running, HIIT, jumping, and activities with greater breast movement.
Build support through construction
- Underband width and stability
- Strap width and configuration
- Neckline and side coverage
- Fabric stretch and recovery
- Lining or power-mesh support
- Cup or removable-pad construction
- Compression and/or encapsulation
- Back design and closure system
Test on the intended body range
- Bounce control during realistic movement
- Underband movement and stability
- Strap pressure and comfort
- Coverage and chafing
- Breathing comfort
- Overall fit and support on relevant body sizes
Validate the claim on the finished bra
A fabric with high recovery may contribute to support, but it does not determine the support level by itself. Confirm the full construction through samples and realistic wear testing before bulk production.
At Call The STYLE, support construction can be developed according to the intended activity, fabric, size range, and brand positioning.
