Measure Your Under Bust
Measure Your Full Bust
Wearing an unpadded bra, wrap a measuring tape around the top of your ribcage. You’re looking for a snug fit - so we recommend tightening on the exhale and noting the smallest measurement to the decimal.
Wrap the measuring tape around the fullest part of your chest, making sure the measuring tape is paralell to the floor. Relax your shoulders and measure where it falls.

Reviews Summary
Generated by AI from 40 most recent customer reviews
Last updated 3 weeks ago
Customers say this sports bra is extremely comfortable and supportive, with many describing it as feeling like they're not wearing a bra at all. The soft fabric and medium support make it suitable for workouts, yoga, and all-day wear. Users appreciate the back strap design and front ventilation features. However, sizing appears inconsistent, with some finding it runs small while others need to size up for proper fit. A few customers report issues with the bottom band rolling up and cup inserts shifting after washing. Some mention the shoulder straps sit too high for certain tops, and there are requests for expanded size ranges and lighter color options.

- Rated 5 out of 5 stars6 days agoVery nice bra
I was very happy with this bra. Great length if you want to wear it on its own but can wear it with a t shirt over it. Only negative is you need to smooth out the pad after washing but it does keep its shape overall!
Jabeen H.Verified BuyerReviewingLongevity Sports Bra - Rated 5 out of 5 stars1 week agoSports bra
This sports bra is less supportive that the the other two styles I purchased. I actually bought this bra as a second of the same style. This bra is everything that they have claimed. I wouldnt run with this bra but pretty much anything else for a better support. It's soft and very comfortable andc washes up great. I machine wash and hang to dry. The first one I bought a year ago does not show signs of wear or elasticity wear. Worth the purchase.
Fern E.Verified BuyerReviewingLongevity Sports Bra - Rated 5 out of 5 stars1 week agoSports bra
Bought in white excellent for low impact workouts and would not have tried on due to being busty but staff told me it’s fine if busty and it’s very comfortable and stylish.
Julie T.Verified BuyerReviewingLongevity Sports Bra - Rated 5 out of 5 stars2 weeks agoAwesome everyday sports bra
Great for lifting, hiking, anything medium impact. Love how smooth it is under shirts and that it doesn’t pull overly hard on neck/shoulders. Good balance of support/comfort.

Merry C.Verified BuyerReviewingLongevity Sports Bra - Rated 5 out of 5 stars2 months agoSo Comfy
Super comfy medium support sports bra. Love how the straps lay in the back. The venting on the front helps give airflow to the girls when working out. Would purchase again
