If I had that much to spend on kids clothes and was silly enough to spend it,I'd enjoy the shopping itself myself.
I don't buy cheap,you only get disappointed in most cases,but I don't see the point in spending a fortune on something that can be stained,torn,or just plain too small,in a very short space of time,cos they are just kids.Let them be kids,they're not toys,certainly not dollies.
I usually spend around £30-40 on a coat ,maybe more now my older children are getting bigger.I do expect to last at least a season,hopefully/usually two,and then it gets handed down to the next one.
