Shoppers - please help me find this top

So after cruising through jane.com, I found a photo of the top I have been trying to find but of course it wasn't for sale on there, just the leggings with it in the photo. Does anyone know where I can get a top like this? Something long enough to wear with leggings this winter, so it definitely has to cover the butt. Also looking for longish cute sweaters to wear with leggings too.
