Hi,
It is definitely licensed. Anything made after the mid 1950s (I forget the exact date right at this moment....it was sometime between 1954-1957) with a Schiaparelli label is licensed.
Isn't this all so interesting? So, if I am getting this, ....the Sam Diamond Mill Co, as US based company, did not make the sweaters, but imported them or distributed them in the USA, hence the RN number. So I might assume the sweater dress was made in Italy, imported by Diamond Mills using that RN #, and with a license fee paid to Schiap for the use of her name. Now I must find out...did Diamond Mills pay for the use of her name, or did the maker of the dress pay for that privilege? As most of what I collect is antique or older than 1930's, I was never one to get into all the Union numbers and RN numbers and such, but I can see how they can solve mysteries!
