What Our Gearhead(R) Experts Are Saying: "I like this for studio sessions where I want something streamlined and supportive. The built-in shelf bra gives enough hold for strength work and low- to mid-impact training, and the compressive fabric feels secure without restricting movement. The open back adds ventilation, and the stirrup leg keeps everything in place. If you're between sizes, I'd size down for the best fit." When we're channeling bold energy and unapologetic confidence, we step into the Not Your Mother's Onesie from Daughter Lessons. Inspired by iconic aerobics silhouettes and reimagined for modern movement, it's built to stand out in the studio and beyond. Crafted from a sculpting nylon-spandex blend, this lightweight onesie delivers compressive support with smooth 4-way stretch. A built-in shelf bra provides dependable hold, while the open back adds breathability and edge. The stirrup leg keeps the fit locked in place, and the no front seam construction enhances comfort during high-output sessions. True to size with a size-down recommendation if between sizes, it's a statement piece designed to move as confidently as we do.
