Lilly Pulitzer “knock off” Dress

This is a Lilly Pulitzer “knock off” dress with the treasure trove print. EUC! 3/4 length belle sleeves with pom-poms and very stretchy material. The size tag is missing so please go by measurements. It has either a medium or a large. But it would fit both because it is super stretchy. The material feels like bathing suit material. Very comfy and light. Approximate measurements are 35 inches length and 18 inches pit to pit.
