Cambridge Romper, Garnet Tattersall

This 18th-century garnet-red design will have you back at the Tattersall Horse Market in London, where the checkered pattern got its name. 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.

About Petite Plume: Sophisticated comfortable sleepwear for children, Petite Plume pajamas and nightgowns are crafted from the most exquisite cotton and the finest attention to detail, from the engraved buttons to the tuckpointing and the yarn-dyed fabric, which then gets brushed for softness. A celeb favorite, Petite Plume has been worn by everyone from GP (Gwenyth Paltrow) to PG (Prince George), making it the perfect monogrammable gift for any child you love. The New York Times even called them an "elevated take on a classic button-down pajama set," we're equally impressed by Petite Plume's origin story: Founder Emily Hikade launched the brand while undercover as a CIA case officer. Their adult sleepwear is made from 100% cotton, while Petite Plume's pajamas, nightgowns, and robes for kids are made with the finest quality cotton and blended with just enough inherently flame-retardant fiber to allow our sleepwear to pass strict CPSC regulations without the use of harmful chemicals. The fabric is preshrunk and yarn-dyed to prevent fading, then brushed for added softness.
