The button at the last part of the jacket couldn't click in so it wasn't useful and the very top gold button fell off so I had to stitch it on. Other than that, great quality, just have to be aware that things like this might happen in your order if you plan to get this.
The Quality is so so god and it fits perfectly. It’s really cozy and comfy to wear🥰 thank you so much
