As it happens with almost every type of clothing, most of the time, it is about finding the balance between the cost and quality of the blouse. Even if there's a correlation between these two, people usually associate higher prices with higher quality.  You can always find great blouses in your local brands at a favorable price. However, some good brands include Forever 21, Vero Moda, Dorothy Perkins, H&M, Femella, and Benetton.
