Does anyone know where I can find a coat like this?

But not the £799 price tag! I love how it appears to fit, not dying about all the buttons though.

I can't help you, but following along. That is gorgeous.

Google full-length herringbone jacket this is one of the cheaper options...Sainsbury's!

Next £140

New Look has one for under £50

Google ankle length herringbone great goat

Cheaper ones will never hang the same though.
