It is usually made of cotton, lace and small butterflies with two or three rows of buttons at the back (if the chest is big, you should wear three rows of buttons, otherwise it will be easy to open). In summer, some women also like to wear strapless clothes, so underwear needs to be bought with no shoulder straps, transparent shoulder straps, or belts hanging directly around their necks. There are many kinds of underwear according to the size of women's breasts. Those with small breasts usually wear "butterflies" with cotton pads or water pads inside, so that women's breasts can usually be held up from bottom to top, and they feel so good that they can almost be confused. Butterflies with big breasts are usually very thin. Some of them even put on clothes in summer. You can vaguely see that "Little Cherry" is more attractive to ordinary girls (lace is the top grade), and girls who are more open below usually wear T-shirts. There is only a crack in the back and a transparent rustling in the front. Dense forests are faintly visible. I can't finish talking for a while. I suggest you go to the women's underwear monopoly, which is more intuitive.
