Twill Madeline Romper | Vintage SweetsOur Romper is made of the softest brushed fabric which will allow your little one to walk, crawl, or relax in comfort. The sleepwear is made from the finest quality yarn dyed cotton and blended with just enough inherently flame retardant fiber to allow it to pass strict CPSC flame retardant laws without using harmful chemicals. The fabric is brushed for added softness, making the sleepwear feel absolutely luxurious, getting cozier after each wash.
