I bought this about 5 years ago for a school excursion, but I never wore it. I hope someone can use it. The back expands widely, so you can wear it even with a school backpack or rucksack on. The item condition is "new, unused," but the tag has my name on it, so that part has been cut off. Please understand. Length: Approximately 74cm School Backpack Coat Color: Yellow系 (Yellow-based) Pattern/Design: Solid
