Clean, supportive, and cut with precision. This top features a modern square neckline and wide-set bonded straps for light support without extra hardware or padding. Double-lined for a gentle, natural hold, it’s finished with bonded seams that lie smooth against the body without bulk or digging. Our custom spacer-lite fabric combines Lycra with soft yarns for high-performance stretch, zero sheerness, and a refined, silky feel. Made for low-impact movement and everything that follows. A strong base, in every sense.

* Non-wire bra sizing can vary by preference and if you're toward the top of a size range and prefer more coverage, you may want to size up. For styles available in + sizes (designed with additional support details for our larger cup customers), we find DD's can be on the cusp - if you prefer more coverage and support, we suggest the + bra equivalent for your band size.
