Needs to be waterproof and warm and under £40 if possible.
I can't (yet) find anything that's isn't shiny material (yuk) or too thin. I'm shocked at Next' s coat collection this year as usually get her one from there but they are awful!
I think I might be struggling because she's just 'graduated' from younger girls ranges to older girls and everything seems too old for her 
Any suggestions gratefully received..
