Vintage 70s Calderon Blue White Red Maxi and similar items

Vintage 70s Calderon Maxi dress. The top is V-neck with dramatic ruffle neckline and long sleeves with trumpet Ruffles at the wrist. The top is chiffon. There is an attached belt that hooks in the back with red fabric background and blue lace overlay. Back zip. The skirt is maxi length and is blue lace with red peekaboo underlay and red chiffon hanging down an extra 2 inches from the hem. There is no fabric content tag. Just the brand tag. No noted flaws. Laying flat measures 56 inches shoulder to hem, 14 inches straight across the waist and 18.25 inches from pit to armpit. There is no size tag, but based on these measurements, I would estimate it to be approximately a modern size small, but please double check measurements to ensure the proper fit for you.
