The blouse matches with a 38, and sits very loosely. You can wear the blouse even with size 40th The blouse is cut very pleasant even on the arms, more powerful upper arms are not an issue. The material is very pleasant and easy, typically thought of viscose and just for the summer. The color and pattern like it very much, it is a darker shade of blue with white-cream-colored printing, and fits perfectly with a pair of jeans and a white blazer. The workmanship is good.
