I bought the shirt and is just too small in my bust so I needed one size bigger. Luckily, I found one on Poshmark. The blouse is sold-out everywhere. Three quarter sleeves with a curve hugging fit. It has some stretch it’s cotton polyester and spandex. I am a G cup and it fits everywhere else perfectly except I can’t get the button closed around my bust. I usually wear a small so I would say it runs true to size depending on your cup size. The blouse has never been worn. I took the tags off because I assumed it would fit. I think I still have the tags if you want them.
