Oriental Influence and Mandarin Collar

I don't know how young I was but I remember my mom, the fashionista, talking about "mandarin collars" and Suzie Wong dresses. I saw the Suzie Wong movie years later and thought about how Hollywood influenced fashion, sort of like the influence The Great Gatsby is having today. Here is a pattern from the late 1950's with "slim-lined Oriental influence....and Mandarin collar."
The envelope is gone with time. The previous owner salvaged parts of the envelope and pasted them on a Manila envelope. Good thing since the front picture and envelope back are in good condition.

A very rare estate sale find.
