VTG German/Swiss dirndl costume dress no tags/see measurements no stretch

Vintage German/Swiss dirndl costume dress no tags see measurements I don't know the history; I'm assuming it's a costume due to its light weight and it has ties in the back instead of a zipper or buttons It feels like cotton. The sleeves are sheer. I found one thread pull in the blue fabric (see pic) and there seems to be slight fading, but overall in good vintage condition Measurements (approximate): 18" pit to pit 15" across at waist 27" across at hip 35.5" from center back to hem No stretch in the fabric
