This window is a strange mix of classic American clothing crossed with modern British wallpaper with a southern twist.
I love the wallpaper they have knocked off for this window display, I'm not sure it goes with the moss/hay on the ground and the Nantucket meets the Hamptons vibe the clothing and furniture in the window gives off but I definitely give them credit for putting the tree in there. I'm thinking the branches attached to the ceiling and hanging down give it a Spanish moss sort of feel.
I have been in love with this Fromental wallpaper for AGES. I used to go look at it whenever I needed to visit the Webster showroom for work. It never had a name or a price so it took a while for me to figure out what it was but I do still love it even if I assume that the only way I'm getting some of this wallpaper is to paint it myself.
