C Cup Sports Bras

While there are many great C cup sports bras on the market, if you need a smaller band (think 8C or 10C), or something a little larger (18C or 20C) finding the right fit for your frame can be tricky at mainstream retailers. Too often, women settle for sizing that isn’t quite right, with many realising only after being properly fitted that they’ve been wearing the wrong size for most of their lives. For C cup sports bras, we’ve made sure our collection has styles in multiple band sizes and for various impact levels, because your body deserves to feel at its best while training hard. If you have a suspicion you’re not wearing the right sports bra size, let us help you find the right fit.

What to Look For in a C Cup Sports Bra

The hunt for a C cup sports bra that feels tailor made for your body requires a few key considerations. Starting with your band fit. Look for a firm and even feel around the ribcage that stays put and doesn’t ride up your back. Next, think about what kinds of movement you’ll be needing your sports bra for. If your exercise of choice is high impact - think long distance runs or short bursts of cardio - the best choice is an encapsulation sports bra or a combination style, which gives better bounce control and separation. If you like a more structured feeling, underwire sports bras are a great C cup option, adding structure and lift without any bulk. When it comes to straps, cross-back or racerback styles give added support and help distribute weight more evenly across your shoulders, keeping your bra secure as you move.

If you prefer a less rigid feel and are a low to medium impact mover (think yoga, Pilates, cycling), then compression bras will keep you well supported. Similarly, a wire-free crop with a firm band might be all you need, depending on your preference.

The fabric of your C cup bra is also something to get right - unlike regular bras, sports bras need to be able to deal with sweat, so moisture-wicking materials are a must to help keep you cool, dry and comfortable throughout your workout.

While C cups have access to a broader range of sports bra styles, we’ve found many women still struggle to find smaller bands in a C cup. At She Science, we've made it a priority to stock these harder-to-find sizes, helping more women experience the comfort, support and confidence that comes from wearing the right sports bra.

 

What is the best sports bra for a C cup?

It depends on your activity. For yoga, Pilates, or low-impact gym sessions, a wire-free compression style or firm sports crop works well. For running or high-impact exercise, look for an encapsulation style or a combination bra with structured cups and a firm band; at C cup you'll start to feel the difference in bounce control.

Can I wear a C cup sports bra for running?

Yes, but the style matters. At C cup, breast tissue moves significantly during running, and a loose-fitting crop or basic compression style often won't provide enough hold. Look for a sports bra rated for high impact with structured or encapsulated cups and a firm band. It doesn't need to be heavy or restrictive; the right fit at C cup can be both supportive and comfortable for even longer runs.

Should a C cup wear an encapsulation or compression sports bra?

Both can work at C cup; it comes down to your activity and personal preference. Compression styles are great for low to medium impact and tend to be lighter and more versatile. For high-impact activity, encapsulation or a combination style (encapsulation plus compression) gives better bounce control and keeps each breast supported individually. If you're unsure which suits you, our fitters can help you work it out in person.

Do C cup sports bras come in small band sizes?

Yes. She Science stocks C cup sports bras from band size 6, including 6C, 8C, and 10C combinations that mainstream activewear brands rarely carry. Use the size filter to find your combination.
