It's nicer than the ones linked because it has some shape to it. It goes in at the waist when done up properly. Straight up and down boxy shapes seem to be very popular on MN for some reason.
I honestly think if it said £150 instead of £850 you would have got less scathing replies. A bit how the expensive handbag threads go.
Personally I think it's nice but I'd pass it by whilst browsing for a coat as it's not what I'm looking for. I'm not keen on how a funnel neck looks on me.
But you're the one who'll be wearing it, if it's the one that makes your heart sing then buy it. Never mind what anyone else thinks. Having seen lots of those threads where the OP ask for help finding an outfit, I know we all have very, very different tastes on here. It's a good thing, it'd be boring otherwise, just not when you're posting a link to your dream coat.
