Unused, but it was a gift, so the storage period is unknown (not new). The back has only the logo at the neckline. Total length: approximately 74 cm from the shoulder; chest: approximately 110 cm. It will be packed in a Nekopos size. Please understand that there may be creases upon arrival. I have a pet. Please refrain from purchasing if you are sensitive, have allergies, or dislike pet hair (there is a possibility of hair adhering during packaging).
