I saw the pajama post and it reminded me to ask: does anyone know of wool, oekotex cotton, or linen nightgowns for little girls? Size 5 and 7. They dream of long, flowy white nightgowns—that Clara in the Nutcracker look—but the only ones sold in the U.S. are polyester and/or have flame retardants. Do any European brands sell nightgowns? I really don't want to have to sew my own. I'm a terrible seamstress.
