Barbie Child's Superstar Pink Box Costume!

I have 2 of these, new, price is for 1. Please see pictures for more information on the costume and sizing, however these are labelled as Girl's 1 size. I am petite 5'2" and I can fit inside, ages 4+ it says. Small parts, a bit tricky to assemble. Packages have a bit of wear, but new and unopened. These are styled after the iconic 1977 Superstar box who was the face of Barbie through the 80s and 90s!
