I ran across this picture of Marilyn before she was Marilyn in a cute little sun-suit
crop-top with short sleeves and a mini skirt, i would guess it has bloomers underneath.
the style reminds me of a set i made from a vintage 40s sewing pattern. you can check it out at my Etsy shop Morningstar84. Cotton plaid with satin details.
