As all said, this coat was custom made for Nina's character But that Etsy one is gorgeous, not sure I'd drop $500 but it's a very close match. I found a vintage pink GAP wool peacoat at a resale store that looks very similar, so you could check second hand shops too. I bought this white scarf also to replicate the Nina look:
The price on the Etsy coat drop!! i 'm getting mine tonight when i get a chance to measure my coats and see if this will fit or if I have to make a custom order!
