This is very cute shirt but..... Shirt is definitely cut small. If you have big boobs it's a definite NO!. I don't have big boobs and it's still too tight to buttons. It's also tight around the arms. A large maybe would have fit me better but I never purchase large shirts ever. Usually a small or medium.

I sized up, I weigh 140lbs, 5’3 tall and bust 36D. Worked perfectly for me. There’s not really stretch, just in the stomach area which is great, but still be sure to size up for a better fit. Fabric is not cheap at all and feels great and thick
