Vintage 60’s Devonette Polytrin Three Piece Ladies Suit! Jacket, Skirt and Pants

Calling Mrs. Brady or Mrs. Partridge! 60’s/70’s Devonette Polytron Rust Color Three piece ladies suit! Great collectible or Halloween costume. No size. Would estimate it to be a medium though the jacket is boxy and the pants and skirt are elastic waist. Not lined. Only sign of wear is the pulling at the pant cuffs (shown in pictures). What a trip back in time!
