1970s Cirette California Black White Psychedelic Geometric Print Maxi Dress Gown

This really cool 1970s Geometric Print Maxi Dress still has a barcode tag attach. This is a very light weight polyester material I believe. Don't see fabric or size tag but definitely a small with little give in the material.
