This is a reversible MA-1 bomber jacket from H&M. It's a reversible type, black on one side and floral on the other. It's a men's jacket, but I think women can wear it too. The size is S in overseas sizing, so I think it's equivalent to a Japanese M size. It felt like a size M when I wore it. As you can see in the 3rd and 4th images, there are some thread snags. Please refrain from purchasing if you are concerned about this.
