Vintage yellow blouse

Shirt is labeled with 16 but would not be a modern size 16. My best guess is that it would best fit size 6-8. (I was ~size 8 when I wore it- seen in last photo from the side) 16.25 in- across the bottom of blouse 17 in- shoulder to bottom of shirt 22 in- sleeve length 100% polyester In good quality, with some slight pilling/ loose threads on front of blouse (pictured)
