Wow, what a great find - Vintage Vanity Fair slip in two colors.  Definitively 1950's with the light blue script tag that reads nylon tricot only.  Bodice in ivory and skirt in midnight blue.  And it's so gently used that it's in near mint condition.  Sized at a 32, measures an XS, refer to measurements listed.  This slip is such a find and so pretty!  Note the one photo highlighting the bottom of the slip shows up like a royal blue which is camera error it is a dark, dark navy or midnight blue as seen in the other images.
