Clothing M3 MG004 coat on Alice's Collections

Hello! Does anyone have this coat? Forgive me if it's obvious, but given that the buttons on the front look decorative I'd like to know if it's closed by snaps, or it's simply pull-over and you have to take off the head.
If it can be opened, do you have pictures of how it looks unbuttoned?

 

That was my guess as well, but I'm doll fashion illiterate
I have a dress on the way and I think this would look nice over the shoulders. I wish Alice had more pictures of the items sometimes.

 

Thanks everyone for clarifying!
