Kids Unisex Onesie
Tuck your little one into all-day-and-night cosiness with this plain unisex onesie in four colours - a head-to-toe loungewear essential designed for bedtime, sleepovers, lazy weekend mornings and snuggly Christmas mornings.
Crafted from a soft cotton-blend brushed knit, this onesie feels gentle next to skin and traps just enough warmth without overheating. Long sleeves and long legs keep kids covered from neck to ankle, while ribbed cuffs at wrists and ankles hold everything neatly in place.
This versatile unisex onesie is the kind of piece children reach for again and again. Wear it as classic sleepwear, layer it over a t-shirt for an extra-warm winter night, or use it as cosy loungewear for movie days and weekend mornings. The plain unprinted finish makes it equally lovely as a wardrobe staple or as a starting point for personalisation.
Care: Machine washable at 40 degrees with similar colours. Do not bleach. Tumble dry low. Cool iron inside out if needed.
