If the bra is too tight, replace it with a bra that is too small. Wear it, the chest will feel oppressive, which is not conducive to ventilation. In severe cases, it will affect the blood circulation of the breast and the normal reflux of lymph. Over the years, the toxins in the chest can't be discharged, which will increase the chances of mastitis, mammary gland hyperplasia and even breast cancer.

When wearing a bra, if the following situations occur, it means that the bra is improperly selected:

1. The breast protrudes from the edge of the cup, indicating that the cup is too small or too pointed.

2. There is a protruding part under the armpit, indicating that the bust of the bra is too small or the side is too narrow.

3. After the arm is raised, the bra jumps up, revealing the breast, indicating that the bust of the bra is too loose.

4. The shoulder strap is embedded in the shoulder, indicating that the shoulder strap is too short and needs to be adjusted.

5. After wearing a bra, if you find red marks around your breasts or feel pain, you should also be alert to whether the bra you are wearing is inappropriate.

So, what kind of bra is suitable? When choosing underwear, we should pay special attention to the size of the bra. The appropriate bra size, preferably the distance between the breast and the bra, can accommodate 1-2 fingers, and feel comfortable and move freely when wearing it. Remember that bras should not be too tight, especially those with steel brackets. The bust must be wider. When you reach out and exercise, there will be no pressure on your chest, and your bra will not come out of your breast. After taking off the bra, there will be no ligature marks around the breast.
