Vintage Pure New Wool Short Sleeve Slip Dress madein New Zealand size 24 thermal

Vintage Pure New Wool Short Sleeve Slip Dress made in New Zealand size 24 thermal long underwear style material with the tiny holes in the pattern I wonder what that’s called, do you know? Good used condition except the bottom has a few dark stains around the hem the top is near new for how vintage this looks. chest 16” length 36” very stretchy I say slip and long underwear thermal because it has that appearance although maybe it’s just a dress🤷🏻‍♀️ semi transparent, natural fiber Sun cover for the beach. I love this thing but it’s been hanging in my closet for years and it wants to be worn by you!
