Straps can play a role in caring for bras, preventing them from falling off without straps and also preventing them from becoming too tight without straps. The strap should not be too narrow, at least 2-3 centimeters wide; The straps should not be too tight or too loose. If they are too tight, they may slip off the shoulders and not provide support for the breasts. It is best to have an elastic band on the bra strap for easy regulation during physical activity.
Bras made from synthetic fibers and wool products pose a risk of fiber blockage in the milk ducts, which can lead to poor milk flow and a shortage of milk in the future. Therefore, it is recommended that pregnant women, parturients, unmarried girls, and women who have not given birth should choose bras made of real silk or cotton fabrics. In addition, the color of a bra should also be carefully chosen, and it is generally advisable to use a color that is similar to one's skin tone. Middle aged and elderly women should choose colors that are soft, while young women can choose colors that are elegant, soft, or bright and stimulating according to their personality, hobbies, and different occasions.

It should not be mixed with other clothing, especially chemical fiber clothes, woolen fabrics, old towels, old pillowcases, towels, and other knitted fabrics, to prevent fine fibers from falling off and sticking to the bra, and blocking the milk ducts after wearing.
As a private item for women, bras are more delicate and susceptible to bacterial attacks. According to relevant research, long-term use of underwear without sufficient ultraviolet radiation can result in several times more bacteria on the surface than regular ones. This means that bras are changed irregularly, and the cleaned bras are not exposed to sunlight, which can further damage your breasts. Furthermore, after prolonged use, bras are prone to deformation, fading, and fail to provide shaping and support.
It is important to have the habit of wearing bras year-round and take them off before bedtime to avoid affecting breathing, blood circulation, lymphatic circulation, etc. The specific massage method is to gently push and squeeze towards the center of the breast from the left, right, and bottom of the breast, without touching the nipple. Push 15 to 20 times a day.
