There are shoulder pads. It opens in the front, and although it's hard to tell due to the design pattern, there are round gold buttons. There is a small, decorative chest pocket on the chest. (I've taken a photo of the area on white paper.) The hem has a double flare design, which I've also photographed on white paper. Please check the photo of the back as well.
