Charcoal flowered blouse from ba&sh, size 8

Gorgeous floral design from ba&sh. Size 2 French women, which is 38-40, or US size 6-8. It fits loose, 6-8 could wear if you like loose-fitting, or could work for US women's size 8-10. I fell in love with this shirt, and bought it online when I lived in France--but didn't understand the sizing and it was too big on me. I bought it used for 100 euros, it was 240 euros new.
