Vintage 70's Floral Cropped Tie Up Blouse

Vintage 60’s/70’s floral cropped blouse. Undershirt and over shirt are attached. Fits like a small, but size tag is worn out (please refer to measurements.) I’m pretty sure it’s from the 60’s/70’s, but I can’t 100% guarantee it. Flat Lay Measurements: ▪️Pit to pit: 19” has stretch ▪️Length: 19”
