1.Mondrian color scheme combination: The top piece is in a sophisticated gray color, which is elegant and low-key, while the bottom part is in a light gray-blue check pattern. The collision of two low-saturation colors creates a gentle and soothing visual effect, full of modern minimalism and light artistry, completely getting rid of the dullness of traditional pajamas. Fine check pattern elements: Compared to large checks, the fine small check patterns are more exquisite, retro and delicate, avoiding the visual expansion effect, making people look more neat and refreshing, and easily creating an effortless fashionable home style. 2. Golden fabric ratio (95% polyester + 5% spandex): This ratio is the key to achieving comfort. Polyester (95%) ensures the fabric's stiffness, durability, and easy stretchability. It is resistant to wrinkling, shrinking, and quick drying, and remains as new after being washed and dried. Spandex (5%) is the essence. It endows the fabric with outstanding elasticity, following the body movement like a shadow, without any constraining feeling. Skin-friendly softness: The fabric is treated with special processes such as brushing or brushing, resulting in an extremely soft and smooth touch. The moment it touches the skin, one can feel warmth and care, as if being gently wrapped by clouds. 3. Three-dimensional Tailoring: The design features a casual yet not bulky three-dimensional cut, ensuring a sense of looseness while maintaining smooth lines of the body shape. This avoids the cumbersome appearance of a "sleepwear gentleman". The overall effect is neat and stylish. Unrestricted in all directions: From the shoulders to the cuffs, from the chest to the hem, there is ample room for movement. Whether it's turning over, stretching, or doing yoga and meditation, one can truly enjoy a sense of freedom. 4. Elastic waistband: The waistband of the pants is made of a wide elastic strip with high elasticity. The elastic band adapts to the waist size automatically, perfectly compatible with various body types, and completely solves the problems of tight waist or sliding of the waistband. The internal workmanship is smooth, without raised labels or stitching, avoiding friction and discomfort during sleep. Strengthening process: The neckline, cuffs, trouser hems, and seams are all strengthened, making them durable and easy to wash. They won't deform or shed balls over time, and the quality is visible. 5. This is not merely a set of pajamas; it is a high-quality home casual wear. It conquers the eyes with its exquisite small-check pattern design, the touch with its golden-proportion fabric, and the experience with its user-friendly elastic waistband. It is a must-have item for those who value the quality of life.
