Looking at Kate's gorgeous coat reminded me that a pastel coat is at the top of my WWW (Winter Wardrobe Wishlist), and it should be on yours as well. I mean, seriously, how much brighter would those dark winter days be if everyone wore soft pinks, greens and blues instead of black, grey and navy?! Below you can find a few of my favourites available at the moment (several of them are available in other colours as well).
P.S. If you are looking for a good RepliKate of Kate's blue Matthew Williamson coat, ASOS has one that is very similar. A custom made one from the Tatiana's Delights Etsy shop is of course also possible. In that case, be sure to send me a message via Etsy regarding a custom listing!
