I don't know if I should really input on this thread regarding the coat. I would have to know the make and fibre content, style, all the technical bits before I say it is worth the money or you are just paying for a label.
If I saw it and weighed all that up, and it seemed highly profitable to buy instead of making it, then I would snap it up there and then. Being a designer myself, it has its benefits such as I am able to whip up anything for dd in a short space of time and whenever I want. But most importantly, no matter how spoilt dd will try to be from aunties and uncles plus cousins, they are held back in buying clothes for her since I can make them. They would go wild and spend ridiculous amounts of money which IMO, she doesn't really need. Food, water and air are staples besides clean clothes, not lots of clothes.
If you want to put a value and say if it is worth it, think about the fabric and style, will go on through the year (passed down) and if it is durable IMO. It also depends on the location of make, a poor country or rich one, child labour, offshore production and the list goes on.
That is me and my soap box done.
