This is a beautiful top. It is the Bowen Top in Mermaid For You by Lilly Pulitzer. It is 94% Rayon and 6% Spandex. It is not meant to be worn tightly. This shirt can be dressed up with skinny black pants, or white jeans or white shorts-that was going to be my pairing. If you follow me you know I owned a Lilly store for years. I am so blessed to have received clothing from reps, and just shoplifting from my store, LOL. We recently downsized houses (like 1/2 the size) & while I love this bungalow the closets are what you would expect fro a 100 year old house. Measurements lying flat Bust 21" It is 20.5" wide all the way down. It is truly beautiful! Watch my sales soon, I am adding a piece or two of Lilly every day.
