Choosing the right sports bra is one of the most important—and underrated—decisions you can make for your fitness wardrobe. Whether you're a yoga enthusiast, a weekend runner, or someone who values support during everyday errands, the right fit will transform your comfort and performance.
But how do you know which one is best for your body and activities? Let's break it down with tips backed by fitness experts, real research, and years of activewear design experience.
1. Match Your Sports Bra to Your Activity Level
Not every workout demands the same level of support. Choosing a bra designed for the wrong activity can lead to discomfort, breast pain, or even long-term tissue damage.
Here's a simple breakdown:
If you're doing low-impact activities like yoga, pilates, or walking, you’ll want a light support bra—soft cups, minimal compression, and stretch-friendly fabric that moves with you.
For medium-impact workouts such as cycling, hiking, or strength training, aim for moderate support. These bras often include compression and wider straps to keep you secure without restricting movement.
If you're engaging in high-impact activities like running, HIIT, or jumping exercises, you need maximum support. Look for encapsulated cups, racerback designs, strong bands, and adjustable straps that offer a locked-in feel.

Tip: Match your support level to the bounce level—higher impact means tighter, more structured support.
2. Get Your Measurements Right (And Update Them Regularly)
Wearing the wrong size is more common than you think—studies suggest that over 80% of women wear incorrectly sized bras.
How to measure:
-
Band size: Measure around your ribcage, just under your bust.
-
Bust size: Measure around the fullest part of your chest.
-
Subtract band from bust to determine cup size.
You can use this interactive sizing calculator from SheScience to double-check your measurements.
Remember: Your size may change due to weight fluctuations, hormonal shifts, or even training changes, so re-measure every 6–12 months.
3. Understand the Support Styles: Compression vs. Encapsulation
There are three main types of support structures, and they matter more than you think:
-
Compression bras: Push the breasts against the chest. Ideal for smaller busts and low-impact workouts.
-
Encapsulation bras: Have individual cups for each breast, giving shape and bounce control. Great for larger busts or high-impact movement.
-
Hybrid bras: Combine both for all-around support.
Choosing the wrong type might feel fine in the store but lead to discomfort during movement. Learn more from Runner's World's sports bra science explainer.
4. Look Closely at Straps, Bands, and Closures
These hidden design details can make or break your workout:
-
Adjustable straps let you fine-tune the fit as your body changes.
-
Wide straps distribute pressure and reduce shoulder strain.
-
Racerback styles offer extra stability for high-intensity movement.
-
Wide underbands keep the bra in place—your support comes 80% from the band, not the straps.
If the bra rides up or digs in, it's not the right fit—no matter how good it looks.
5. Prioritize Breathable, Sweat-Wicking Fabric
Moisture can lead to skin irritation, breakouts, and odor. Your bra should feel like a second skin—keeping you dry without clinging.
Look for:
-
Nylon and polyester blends with elastane for stretch
-
Mesh inserts for airflow in sweat-prone areas
-
Moisture-wicking technology (avoid 100% cotton)

6. Don't Underestimate Style and Versatility
Let's be honest: we're more likely to wear what we love. A sports bra that looks good and feels good gives you confidence, in and out of the studio.
Current trends include:
-
Sleek, square necklines
-
Open-back designs
-
Cropped lengths that double as tops
-
Muted tones or bold color-blocking
At CRAVEBYFW, we design sports bras that meet all the above—function, comfort, and effortless style.
7. Try It On, Move Around, and Trust How You Feel
Before you commit, do the bounce test:
-
Jump, twist, bend, and stretch.
-
The bra should stay in place.
-
You should feel supported, not squished.
When in doubt, ask yourself:
-
Do I feel compressed or supported?
-
Is anything digging, pinching, or riding up?
-
Do I feel like I can wear this all day?
If it's a "yes" to comfort and confidence—you've found your match.
