Sheer pastel mint scallop collared blouse

Sheer pastel mint scallop collared blouse. The most adorable collar! Vintage, brand is Katz and of course the tag is cute too! Pretty sure this is for sleepwear? No marked size tag but I would guess a large but it fits a medium loosely as shown on me in the pics! Has a pocket. Could be a cute thing to wear over tank tops! flaw: there is some distressing throughout the collar edges as shown on last photo. Measures 22.5 inches pit to pit (45 inches) and it is 25 inches long. Please compare measurements to your own to make sure it fits. Used item, has been washed.
