Super cute light weight sweater from Theory. The unstretched measurement is below. This sweater stretches. My approx measurement is also listed for reference. I still can wear this sweater. I only wore it to trip to NYC in December, 2023. It was so light and very comfortable. I hate to let it go but I live in Florida. I don't need it any more.
