repipi jumper Size is S. For reference, my child wore this until they were wearing size 160 clothing. I think it's around size 150-160 (please use this as a reference only). This item was worn by a child. Please refrain from purchasing if you are not comfortable with used items or are overly sensitive to condition. Please refrain from making claims or returns. It will be shipped in as small a package as possible. Instant purchase is OK. Thank you.
