This ultra-soft baby sleepwear set features a delicate peach-pink ribbed knit construction made from premium 'Youkesi' (优可丝) lyocell fiber derived from wood pulp—labeled A-class for safety and comfort. The long-sleeve top has a gentle snap-button front closure and rounded neckline with pink trim, while the matching full-length pants offer elasticated waistband and ankle cuffs for snug, non-restrictive fit. A close-up inset highlights the fabric’s fine vertical ribbing and sheer-lightweight texture, emphasizing its breathability and moisture-wicking properties ideal for sensitive infant skin. Designed for newborns to toddlers (0–24 months), this set excels in summer nights or air-conditioned environments, providing gentle thermal regulation without overheating. The minimalist aesthetic, subtle colorway, and functional design make it perfect for daily sleep, hospital discharge, or gentle layering under swaddles. Fabric is certified hypoallergenic, OEKO-TEX®-compatible, and machine-washable for easy care.
