This pretty and feminine parka looks like a dress with its ruffled skirt. It stretches a lot for a snug fit, including around the armholes, so skinny arms won't slip out. This paired with the long skirt make it great for longer, skinnier dogs with narrow waists. It's fleece lined and generously padded to provide a good amount of warmth.
Depending on the size, this coat has between 3" and 6" of stretch in the chest.
