Blackline Bikinis is where sport meets seduction, and function meets freedom. Designed for life in motion, our swimwear blends minimalism with bold energy, echoing the rhythm of the sea and the strength of those who wear it.
Each piece is thoughtfully crafted to move with you—from the lane lines to the shoreline, from high tide mornings to golden hour dips. Founded by former collegiate swimmer Molly Sharp, the brand draws from a lifetime in the water. The signature black line at the bottom of the pool—symbol of grit, focus, and perseverance—inspires our name and our ethos.
At Blackline, we believe in swimwear that feels like a second skin, elevates your confidence, and invites you to live a life that’s both active and effortless, fierce and free.
