This is an old "ohifu" (a type of vest worn by young children). I bought it intending to use it, but I never did. I'm still hesitant to sell it, so I'm not really considering lowering the price. It's old, so please check the photos carefully for any dullness or stains. I hope to pass it on to someone who can appreciate the texture that has come with age. It's 54.5cm, a bit larger than a standard ohifu, so it can be worn by children of a wide range of ages.
