Kid's Twill Pajama Set in Whale Print from Petite Plume. Size 8. Gently used. Little whales are cute and nautical on these softly brushed cotton-blend pajamas styled perfectly for your little one with piping, lapels and a pocket. 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. Snuggly soft and becomes more buttery with every wash.
