If you want to do European double eyelids, you'd better consult a doctor first to see the actual situation of your eyes. The doctor will give some advice to determine which double eyelid method is more suitable for you.
More than 3 months ago, my classmate just made a double eyelid surgery, and it looks good. Her eyelids are thin. The price seems to be around 2000 yuan. She did it in Shanghai, and you can consult the hospital for specific expenses.
