F.O.KIDS Gray button-up cardigan Size 130 Front pockets Filled with batting, fleece-lined This cardigan is thick. I think it's good as a jacket. I was using other jackets, so I only wore it once for going out. I had my sisters wear them, so there are different sizes available. How about for siblings with a year difference in age? Shipping is planned via either Nekopos or Yu-packet Post.
