This two-piece base layer set features a cohesive white background adorned with an all-over black crescent moon print, creating a bold yet minimalist streetwear aesthetic. The long-sleeve top is form-fitting with a round neckline and full-length sleeves, while the matching leggings extend to the ankles with integrated foot coverage—ideal for layering or as standalone loungewear. Notably, the waistband of the leggings is solid black (as indicated in Chinese text: '大货腰头是黑色的'), providing contrast and structure. Fabric appears to be stretchy, lightweight synthetic blend (likely polyester/spandex), offering comfort, breathability, and slight compression for daily wear or light activity. The design evokes celestial, avant-garde, and Y2K-inspired trends—perfect for urban casual styling, studio sessions, or as thermal undergarments in cooler seasons. Pair with oversized outerwear or cropped jackets to highlight the graphic pattern. No visible brand logos or tags are present in the image, suggesting a private-label or independent designer origin.
