Finished and it fits well! Happy! :)

Found some old buttons after my grandmother. They are not equal, but I think it will be nice to use them anyway.

A bit difficult to seem in the sleeves and make them fit properly. I guess it was mostly because I have little experience in seeming knitted pieces together. Had a lot of help in this tutorial from Youtube
