The whole outfit, in one gesture.
The Line is the piece you reach for when the morning should already feel decided: a long-sleeve one-piece with a built-in bra, a high neck in front and an open back behind — covered where the day needs it, free where the practice does.
The fit follows one unbroken line from shoulder to thigh. The shaping back seam follows you through every roll-down, the contoured hip seam defines without digging, and the matte knit holds softly the entire way — held, never squeezed. Thumbholes carry the sleeves over your hands for the cold walk to class.
- Open-back design with a low-profile clasp at the neck
- Long sleeves with thumbholes
- Shaping back seam and contoured hip seam — a lifted, defined fit
- 90% nylon, 10% elastane — soft, matte, high-stretch with full recovery
- Shorts finish at the upper thigh with a clean edge
