What makes Brilly so special?
Brilly isn’t just another sports bra—it’s a complete reinvention of support. While traditional bras rely on outdated design solutions, we engineered the patented Tri-Balance technolgoy that prevents upward movement and adapts to your body, not the other way around.
How do I find my perfect size?
Our bra is designed to adapt, but getting the right size is key. Check out our [size guide] or talk to a fit expert for a personalized recommendation.
Can I wear this all day, not just for workouts?
100%. It’s designed for movement and comfort, so whether you’re crushing a 10k or running errands, Brilly has your back (and front).
What’s the fabric like?
Unlike most high-support bras, we use a woven, four-way stretch fabric that’s lightweight, breathable, and incredibly durable.
What if I’m between sizes?
If you're between sizes, we generally recommend sizing up for more comfort or sizing down for a snugger fit. The adjustable straps and band let you fine-tune your fit.
