MIKIHOUSE Miki House HOT BISCUITS Hot Biscuits It's a free size, but it says 70-90, so I think it can be worn for a long time, from baby to around 2 years old. Length is about 37 cm. It's a poncho, but there are buttons on the sleeves so you can put your arms through. It looks incredibly warm! I received it as a baby shower gift, but my child didn't want to wear it, so I only tried it on once. (I took off the tags because I intended to have them wear it.)
