Unisex Cotton Boneless Butterfly Newborn Jumpsuit

Crafted with high-density flat-seam construction (12–14 stitches per 3cm) and friction-free boneless seam technology originating from Henan, this sweet side-cut butterfly romper (Item Number: 2507cb-p) merges classic monk-suit utility with gentle newborn tailoring. Tailored specifically for newborns and young infants aged 0 to 1 year (spanning height metrics from 52cm to 66cm), it features a comfortable non-hooded neckline, an easy single-button side closure for delicate dressing and diaper changes, long-sleeve coverage, and thoroughly finished seam construction with all excess threads trimmed clean.

Engineered for versatile, year-round wear without seasonal limits, the 100% pure cotton fabric delivers exceptional skin breathability, natural temperature regulation, and soft tactile comfort against sensitive infant skin. Certified under strict Class A safety standards for direct newborn contact compliance and inspected under high-precision AQL 1.0 quality sampling guidelines, this durable one-piece jumpsuit retains its smooth structural finish, flat seam integrity, and subtle side-slit styling through routine daily wear and laundering.

Sourced with ready-stock availability for domestic catalog and retail distribution, each long-sleeve butterfly romper comes supplied with basic protective packaging and removed collar labels for effortless private re-labeling. It is offered in two sweet pastel colorways—Green Wings (Side Cut Bodysuit) and Pink (Side-Slit Bodysuit)—across a newborn height-matched sizing scale: 52cm, 59cm, and 66cm.
