Barbie comes in a blue dress covered in blue and yellow hearts She is wearing hot pink glasses Part of the new diverse Barbie dolls series Barbie partnered with the National Down Syndrome Society to design a Barbie doll with Down syndrome that celebrates this community. Meaningful symbols are incorporated throughout her outfit, and the blue and yellow color palette represents Down syndrome awareness. The three arrows in some of the hearts on the print represent the third 21st chromosome that individuals with Down syndrome have, and they point outwards to represent rising up and moving forward.
