1. The first one is the most popular dimensionless model of ubras. I think this model has no size limit, and it is claimed that A-C can be worn, but I still don't think it is suitable for big breasts and small breasts. A flat-chested friend said that wearing his outstretched arm would run. I'm 80C, and I feel very embarrassed. On the positive side, the fabric is quite good, and I just didn't go out for the exam at home, so I wore it for a long time. It seems that my underwear and chest are "cooked" and quite in tune. The second and third pieces are large cups with square collars. I consulted the customer service before the second purchase, and the customer service said that I was more suitable for this model, so I bought the gray one. Sure enough, this one is much better than the one without size. The bottom of this model is relatively wide and stiff, so it can be propped up without running off the chest. Compared with other one-piece linings I have worn, this one looks better on my chest. Of course, it is not perfect. At first, I felt a little cramped, especially when I was sitting, I felt a little uncomfortable touching the meat on my stomach (of course, this may be my fault, not my underwear's fault).
