Set of two robot costumes. Only worn once for each costume. Woman robot dress is a size medium. Will fit a size 4-8. PLEASE NOTE: I altered the womens costume. The sleeves were ridiculously small, so I cut them off. It is now sleeveless. When worn, this alteration is not obvious. I saved part of the sleeves and made cuffs. Toddler robot is for size 18-24 months. Toddler robot is in original condition. If you have questions, please let me know!
