I bought the medium, 5'5" 150 lbs, and it fits perfectly. The button and crossover piece are lovely and add to the vibe. It is very comfortable and classy LOVE IT!
Just remembered this unique top was in my spring line-up. It's great for camouflaging figure flaws and also adds an artistic flair to my wardrobe! The blues go well with denim or navy pants/jackets.
