BingerlilyWomen's Casual Long Sleeve Tunic Tops Crew Neck Color Block Blouse

Does this run true to size? I’m 5’6” and 130 I feel like I’m between small and med. any suggestions?

I bought the blue and black one but the tag does not show the fabric info. What is the polyester content?

How heavy is the fabric? Is it the weight of a jersey t shirt or hevier?

Where is this shirt manufactured.
