I'm not entirely sure because I cut off the tag, but I think it's probably UNIQLO! I don't know the size either, but I think it's around 100! Here are the measurements, so please check them before you buy (^ー^) My daughter wore this often when she was little, so it shows signs of wear! Shoulder width 28cm. Length 39cm. Width 33cm. Sleeve length 31cm - Color: Red - Design: Hooded - Pockets: Side pockets - Material: Fleece If you have any questions or would like to negotiate the price, please comment (^ー^) Thank you for looking!
