假设你是一家女鞋销售网店的店主,请写一封邮件回复以下这封买家邮件。 Dear seller, I am interested in your product-Item No. WL-004. Are these boots made of genuine leather? And I am not sure about the US size. My foot length is 23. 5cm and I always choose size Euro size 37. So, would you please recommend the US size for me? Thank you. Have a nice day !
