CLASS brand striped blouse

This colorful CLASS brand striped blouse is giving off major 70s vibes! I believe this is an Italian brand, it's labeled size 44, which is an 8 or a medium in US, but please see measurements! This blouse was tight across my shoulders and this is why I'm selling. The shirt pulls over your head and has one button. There is a tiny bit of stretch, but not much. The colors are amazing! Measurements (lying flat and approximate): Pit-to-Pit - 18" Shoulders - 14" Length from Shoulder - 22.5"
