I cannot tell from the photo and description what the fabrics of the blouse exactly is. I guess it is light but actually it is a bit heavy. Luckily the blouse is loosely fit and quite comfortable to wear. When I try on with a pair of black shorts it looks exactly the same as what is worn by the model! I will wear it on working days, in which I go out early in the morning, and stay in the workplace with air-conditioning!
