Review on Women'S Cold Shoulder Blouse Tops V Neck Cut Out 3/4 Sleeve Summer Open Back Tunic Shirt by Nikki Ramsey

I love the shirt but it's about a half size too small. I'm 5'6" weigh 145 lbs and usually wear a large. Because I have broader shoulders and large breasts some shirts are too tight across the chest but this shirt fits fine everywhere except the for arms. They're tight enough for the material leaves red marks on my skin. I don't know if going up a size would be better because it fits everywhere else.
