To tell the truth, it's comfortable to wear and breathable. I'm a c cup. I specifically asked the customer service lady when I ordered. They said the size was European and American standards, so I ordered a smaller size, which was really good, but it's hard to say. Maybe I was proud when I ordered it myself, but I was too young to say. I may have misled the customer service at this time, so it is not ideal to buy it for Ali. Personally, I think this is a fact. Are you colleagues blinding our consumers? Let's call and ask more questions. Don't trust anyone. After all, they have never used it themselves. These people don't know anyone I think it's not bad. Share it with Meimei who wants to buy it. I hope everyone will keep their eyes open and ask more customer service. They are very enthusiastic.
