Finding the right sports bra is about much more than just picking a pretty color or grabbing whatever's on sale. It's an essential piece of athletic equipment that can significantly impact your comfort, performance, and even long-term breast health. In this comprehensive guide, we'll walk you through everything you need to know to find your perfect sports bra match.
Why the Right Sports Bra Matters
During physical activity, unsupported breasts can move in a figure-eight pattern, with movement in all directions—up and down, side to side, and forward and back. Research shows that breasts can move up to 14cm during high-impact activities! This movement stretches the Cooper's ligaments—the connective tissue that helps maintain breast shape. Once stretched, these ligaments don't recover, which can lead to premature sagging and discomfort during exercise.
A properly fitted sports bra can reduce breast movement by up to 78%, protecting your breast tissue and allowing you to exercise comfortably and confidently.

Understanding Support Levels
Sports bras typically come in three support levels, each designed for different types of activities:
- Light Support: Ideal for low-impact activities like walking, yoga, or Pilates. These bras typically feature soft, stretchy fabrics and minimal construction features.
- Medium Support: Suitable for moderate-impact activities such as cycling, hiking, or strength training. These bras offer more structure and often include features like wider bands and adjustable straps.
- High Support: Necessary for high-impact activities including running, HIIT workouts, or team sports. These bras incorporate the most robust construction elements like encapsulation cups, compression panels, and reinforced straps.
At SKINV Club, our Breathe Yoga Bra provides medium support perfect for yoga and low-impact training, while our Endurance Sports Bra delivers high-impact support for intense workouts.
Finding Your Perfect Fit: Size Matters
Studies show that up to 80% of women wear the wrong bra size, and this problem extends to sports bras as well. Here's how to find your correct size:
Measuring for Band Size
- Using a soft measuring tape, measure around your rib cage just under your bust, keeping the tape level and snug.
- If the measurement is an odd number, round up to the next even number (e.g., 31" would become 32).
- This number is your band size.
Measuring for Cup Size
- Measure around the fullest part of your bust, keeping the tape level and loose enough not to compress breast tissue.
- Subtract your band measurement from this bust measurement.
- The difference determines your cup size: 1" = A, 2" = B, 3" = C, 4" = D, and so on.
Remember that sports bra sizing can vary between brands, so always check the brand's specific size chart. At SKINV Club, we provide detailed size guides for each of our sports bra styles to help you find your perfect fit.

Sports Bra Construction Types
There are three main construction types for sports bras, each with different benefits:
- Compression Bras: These work by pressing breast tissue against the chest wall to restrict movement. They typically have a sleek, minimalist design and often come in pullover styles without clasps. Best for smaller cup sizes (A-B) and low to medium impact activities.
- Encapsulation Bras: These separate and surround each breast in individual cups, similar to everyday bras but with more supportive materials. They're ideal for larger cup sizes (C and above) as they reduce movement while maintaining natural shape.
- Combination Bras: These offer the best of both worlds, using both compression and encapsulation techniques. They're excellent for high-impact activities across all cup sizes, especially D cup and above.
Our Endurance Sports Bra uses a combination approach, with molded cups for encapsulation plus compression panels for maximum support during high-impact activities.
Key Features to Look For
Straps
- Width: Wider straps distribute weight better and reduce pressure on shoulders, especially important for larger cup sizes.
- Adjustability: Adjustable straps allow for a more customized fit and can be modified as the bra stretches over time.
- Style: Racerback or cross-back designs provide additional support and work well for activities requiring a full range of arm motion.
Band and Closure
- Width: A wider band provides more support and stays in place better during movement.
- Closure Type: Back clasps allow for a more adjustable fit, while pullover styles are sleeker but less adjustable.
- Elasticity: The band should be firm but comfortable, with enough elasticity to allow deep breathing but not so much that it rides up.
Fabric and Construction
- Moisture Management: Look for moisture-wicking fabrics that draw sweat away from the skin to keep you dry and prevent chafing.
- Breathability: Mesh panels or ventilation zones enhance airflow in high-heat areas.
- Seams: Flat, covered, or minimal seams reduce the risk of chafing and irritation during repetitive movements.
- Cups: For encapsulation bras, look for molded cups that maintain their shape without adding bulk.
The Perfect Fit Test
Once you've selected a sports bra, perform these checks to ensure it fits properly:
- Band Test: The band should be snug but allow you to take a deep breath. You should be able to fit two fingers between the band and your body—no more, no less.
- Strap Test: Straps should feel secure without digging into your shoulders. You should be able to fit two fingers under the straps.
- Cup Test: There should be no spillage over the top or sides of the cups, and no wrinkling in the cup material (which indicates the cup is too large).
- Movement Test: Jump up and down, swing your arms, and mimic the movements of your typical workout. Your breasts should feel secure with minimal movement.
- Comfort Test: There should be no points of irritation, pinching, or chafing. If there are, this isn't the right bra for you.
Sports Bra Care and Longevity
To get the most out of your sports bra investment:
- Rotation: Have multiple sports bras in your rotation. The elasticity needs time to recover between wears.
- Washing: Wash in cold water on a gentle cycle, preferably in a mesh laundry bag to prevent straps from tangling.
- Drying: Air dry your sports bras when possible. Heat breaks down elasticity faster.
- Replacement: Replace sports bras every 6-12 months if worn regularly, or when they start to lose elasticity or support.
Conclusion: Invest in Your Performance and Comfort
A high-quality sports bra is an investment in both your athletic performance and your long-term breast health. By understanding your support needs, finding your correct size, and knowing which features to look for, you can select a sports bra that enhances your workout experience while providing the protection your body needs.
