This is from my personal collection!  Vintage 1940s dress in navy blue lace paired with a later (1970s? maybe earlier) blue dress slip. Side metal zipper on the dress. Slip has lace trim, metal hardware and adjustable straps. Excellent condition apart from a few light marks that are well hidden in the navy blue color. See them in the last photo. 

Dress has no tags. No size tag. Slip is a size 38. Please refer to the measurements in inches listed below, and leave enough room for ease of movement.
