Vintage 80s Blue Day Dress Puffed Sleeves Pink Belt Betsy's Things

Soft, cottony, summer dress that can be worn as a loose smock or as a cute, cinched waist frock thanks to the pink, sash tie belt it comes with. Sleeves are half length, puffed at the shoulders, and feature elastic at the cuff. There is a narrow, mock collar and button down closure at center of torso, above the yoke seam. Note the gentle pleating under the yoke down the wide ruffled panels at the skirt. Unlined.
