I am selling this lovely coat my mum bought my daughter for school, I didnt have the heart to tell her I have already bought her one! It is lovely and warm with a pink fleecy material on the inside. The hood is detachable. It was form Tk Maxx and cost £14.99 (not sure of the rrp)
My daughter is in age 2-3 coats from Next and this fits her fine also, so I would say between 18-24 and 2-3 this should fit fine.
