This coordinated activewear set features a ribbed-knit sports bra with wide shoulder straps, square neckline, and cropped silhouette for moderate support and stylish comfort. Paired with high-waisted leggings in matching textured fabric, the ensemble offers seamless stretch, moisture-wicking performance, and flattering compression fit. The Belgian Blue (‘比利时蓝’) hue is a soft, muted gray-blue—sophisticated yet versatile for studio workouts, yoga, Pilates, or athleisure wear. Fabric appears to be premium recycled polyester-spandex blend with vertical ribbing for enhanced structure and tactile appeal. Flatlock seams minimize chafing, while the waistband on the leggings provides gentle tummy control without digging. Ideal for daily fitness routines or casual layering under oversized tops. The minimalist design emphasizes clean lines and functional elegance, suitable for women seeking both performance and aesthetic cohesion in their active wardrobe.
