Fab ! Vintage THE LILLY Lilly Pulitzer Early 1960s dress size 10 cotton belted L

Fabulous vintage very early THE LILLY Lilly Pulitzer dress This tag belong to the very early piece of Lilly Pulitzer dresses when the company was first established in the 1960s Very rare and highly collectible now The size is not marked, it feels like it would fit a variety of sizes , most comfortable M-L range, or 8-12 range.  Bust measures about 22 inches laid out flat.  The dress is in excellent condition for its age! At some places the flower design is brighter and in some places its more faded. The belt is coming off a bit. It's a super easy fix, but I want to leave everything is found.  The material feels like cotton.
