It has no label, but it is identical to another dress I found on the Internet (Raimbow Dress (1970) Montreal) which is possible since I found it near Quebec City.

It is ivory/cream (I put a color photo as reference).

I put in pictures some measures, write me for any question.  As an indication for size, I usually use small (but I have a wide chest, which is why I can’t close it completely) and I measure 5'2''.  

She has a button in the back, I don’t know what it’s for.  One of the two pieces of the top zipper fastener is missing.  It has a small hole easy to repair and each side of the dress has about 1 1/2'' of fabrics for fit.  

There may be other wear marks that I have not seen despite my inspection.  It is a vintage dress that has most likely already been worn and traces of wear are normal.
