50s/60s Blue Crochet Lace Long Sleeve Wiggle Dress Dress By Sydney North CaliforniaVintage 50s early '60s mod cobalt blue cocktail sheath wiggle dress with crochet lace sleeves. Gorgeous holiday dress in what I would describe as a medium weight polyester or acetate crepe. The sleeves are an open lace floral pattern and very pretty. The wrists are fitted with zippers at the wrist. The dress has a round ring collar and closes with a zipper at the center back. Fully satin lined with bust darts and a hook and eye closure at the neck.
