Germany was reunified in 1990. It's odd that the label says 'Western Germany' rather than West Germany though.
However the care labels are good clues for dating. Their presence means it's almost certainly post 1970. They look like early versions of the symbols, especially the iron symbol (though I can't see it very well), and they lack the tumble dry symbol that was introduced in 1985-87.
So that narrows it down to 70s to mid 80s. I'm seeing late 70s / early 80s, in the graphic design.
Let' see what others have to say though.
