This adorable girls summer outfit is hand sewn. It features a sweet butterfly design in black on an orange background. I think it is cotton. I'd describe the fabric like a lightweight vintage cotton bedsheet. The hem could be let out on the top to make it longer. It does need some mending (see photos), but overall, it's in good shape considering it's age.
