This is a very lovely dress. I bought it in Singapore. I wore it once. It's not cotton. I think it's polyester. I'm not an expert, so I apologize if I'm mistaken. It has a lining. It's not see-through. It shows a lot of the shoulders, so you can wear a shawl or a thin cardigan over it for a stylish look. I plan to send it in a compression bag for packaging, so I would appreciate your understanding. I think it's good for going out.
