The elegant details on this classic nightgown remind us of yesteryear. With the intricately designed placket and versatile collar, it has stunning attention to detail. This nightgown is a lightweight, very soft flannel.  Petite Plume debuted the first-ever chemical-free, flame-retardant fabric for children's sleepwear. Fine yarn-dyed cotton is blended with a touch of inherently flame-retardant fiber to pass strict CPSC safety laws without relying on harmful additives. The moisture-wicking twill weave is crisp, comforting, and cozy. It's brushed for snuggly softness and becomes more buttery with every wash. In our luxurious sleepwear, your little one will be tucked in love and off to dreamland. Bonne nuit.
