Zimmerman Peggy Bow one shoulder swimsuit sz 4 ivory white

Beautiful like new fully lined Zimmermann Peggy Bow one shoulder ivory white swimsuit-measurements shown in pictures. Tags were cut out all that remains is shown. I don’t think it was ever worn. By the measurements I think it would fit a SZ 4? Please see measurements as this is not returnable. There is a very light mark on inside by tag as shown in pic 4. NOT seen from outside. See all pictures as they are part of the description.
