C Cup Bras

Don't assume a C cup bra will fit just because you've worn that size before! Cup size is relative to band size, meaning a 34C and a 36C, while both C cups, will have different volumes and fits. For the best fit, accurately measure both your bust and underbust. Our "How to Measure Bra Size" guide can help you find your perfect match.

When choosing a C cup sports bra, prioritize support, comfort, and moisture management. Look for high-support designs with secure fits to minimize bounce and prevent chafing. Breathable, sweat-wicking fabrics are essential for keeping you dry and comfortable during intense workouts. Triumph's diverse sports bra collection offers styles for every activity level, ensuring you find the perfect combination of support and comfort.

While a 38C, 36C, and 34C share the same cup letter, they fit differently due to varying band sizes. A 38C will have the largest overall volume. If a 36C band feels too tight, consider these sister sizes: a 38B (larger band, slightly smaller cup) or a 34D (smaller band, slightly larger cup). Experimenting helps determine the most comfortable and flattering fit.
