Core Black Bikini Bottom
More coverage, same freedom.
The Core Bottom offers a low-to-mid rise fit with slightly fuller coverage while keeping that cheeky Bearass edge. Made with FlexFlo™, our patented single-layer fabric that’s smooth, flexible, and fast-drying, it’s designed to move with your body and disappear under clothes — the ultimate base layer for wherever the day takes you.
Let customers speak for us
So comfy. The shape is nice and it doesn’t dig in anywhere. I’ve already worn it for a beach day and a hike, no complaints at all.
Didn’t expect to like it this much, but the fit is spot on. Supportive without being stiff. Really impressed.
Great experience overall. Shipping was fast, the packaging was cute, and everything fit just like the site described. I’ll definitely order again.
This top fits so well. It’s soft, comfortable, and somehow stays perfectly in place without feeling tight. I’ve been wearing it nonstop.
Fits a little snug but true to size for a small, looks great!
Absolutely loved these bikinis! Perfect fit and seamless lines. Definitely recommend these
Can't wait to spend a day at the lake in these! So comfortable and cheeky!
Had an issue with sizing on a top. Return was easy though I did have to pay a restocking fee so I didn't get a full refund. They did send me a new top for free without me even asking for it, the new top and different size fit great!
The perfect fit and just the right amount of coverage. Love that they don’t dig in or move around! For someone who’s built very rectangular, I’ve never found another bikini bottom that fits this well.
Love love love my Bearass bikinis!! They fit so well and don’t move around (so no wardrobe malfunctions here)!! Definitely a must try!
SO happy to have found Bear Ass… finding comfortable bikinis that are cute is so difficult! These are hands down the softest, buttery and beautifully made pieces. I started wearing them as undergarments too!! Such an affordable price and flattering cuts. Definitely the most versatile swim suit ever!! Will be purchasing every collection >>❤️
