This blouse is made from cotton, and so when you order order a size up. I wear a med.size 10, I found it to be too tight around the arms. I returned it with no problems from Great Offer Stock and got the large...perfect! You dress the blouse up or down. I wore it to a luncheon and received many compliments. The cotton is cool and breathable, and the tan/ beige trim makes your accessories easy to match. Buy it!
